CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of priority of ProvisionalPatent Application Serial No. 60/079,143 filed Mar. 24, 1998.

FIELD OF THE INVENTION

[0002] The present invention relates generally to gaming machines and,more particularly, to a gaming machine having various play featuresrelating to a board game.

BACKGROUND OF THE INVENTION

[0003] Gaming machines, such as slot machines, video poker machines andthe like, have been a cornerstone of the gaming industry for severalyears. Generally, the popularity of such machines with players isdependent on the likelihood (or perceived likelihood) of winning moneyat the machine and the intrinsic entertainment value of the machinerelative to other available gaming options. Where the available gamingoptions include a number of competing machines and the expectation ofwinning each machine is roughly the same (or believed to be the same),players are most likely to be attracted to the most entertaining andexciting of the machines. Shrewd operators consequently strive to employthe most entertaining and exciting machines available, because suchmachines attract frequent play and hence increase profitability to theoperator.

[0004] One concept which has been successfully employed to enhance theentertainment value of a game is the concept of a “secondary” or “bonus”game which may be played in conjunction with a “basic” game. The bonusgame may comprise any type of game, either similar to or completelydifferent from the basic game, which is entered upon the occurrence of aselected event or outcome of the basic game. Generally, bonus gamesprovide a greater expectation of winning than the basic game and mayalso be accompanied with more attractive or unusual video displaysand/or audio. Because the bonus game concept offers tremendousadvantages in player appeal and excitement relative to other knowngames, and because such games are attractive to both players andoperators, there is a continuing need to develop gaming machines withnew types of bonus games to satisfy the demands of players andoperators. The present invention is directed to satisfying this need.

SUMMARY OF THE INVENTION

[0005] In accordance with one aspect of the present invention, there isprovided a gaming machine with a feature allowing the player to select agame token. The gaming machine comprises a processor, a selectionelement and a display. The processor is operable to execute a gameprogram defining a plurality of stations about a game board traversableby a game token. The selection element is operable to select, inresponse to player input, a game token for illustrating movement betweenthe stations, and the display is operable to display, under control ofthe processor, the selected game token at one or more stations on thegame board determined by execution of the game program.

[0006] In accordance with another aspect of the present invention, thereis provided a feature allowing the player to predict and wager onlanding position(s) of the token identifier. The gaming machinecomprises a processor operable to execute a game program defining aplurality of stations about a game board traversable by a tokenidentifier. The feature comprises selecting, in response to playerinput, a predicted position of the token identifier to be determined byexecution of the game program, the predicted position corresponding toone of the stations on the game board. Then, the game program isexecuted under processor control to determine a true position of thetoken identifier. The processor compares the predicted position of thetoken identifier to the true position of the token identifier, and apayoff is awarded to the player if the predicted position corresponds tothe true position. In one embodiment, a bonus payoff is made if thepredicted position was reached in response to a target movement value.

[0007] In accordance with still another aspect of the present invention,there is provided a gaming machine with a feature allowing the player toobtain deferred-execution instruction(s) which are exercisable by theprocessor to override later-issued instruction(s) otherwise to beexecuted by the processor. The gaming machine includes a processoroperable in a basic mode and a bonus mode, respectively, to select basicgame and bonus game outcomes. A display is provided for displayingindicia of the selected outcomes. The processor issues game controlinstructions associated with the respective indicia. The game controlinstructions include nominal executable instructions adapted forexecution by the processor upon display of the respective indicia and atleast one deferred executable instruction adapted for deferred executionby the processor. The deferred execution instruction might occur in thebasic game and be exercised in the bonus game. In one embodiment, thegame control instructions include an end-bonus instruction (e.g., GO TOJAIL) which nominally cause the processor to end the bonus game, and thedeferred executions include an override command (e.g., GET OUT OF JAIL,FREE) executable to override the end-bonus instruction.

[0008] In accordance with yet another aspect of the present invention,there is provided a feature in which movements of the token identifierare determined according to movement tables corresponding to the variousstations of the game board. The gaming machine includes a processor anda game memory. The processor is operable to execute a game programdefining a plurality of stations about a game board traversable by atoken identifier. Movements of the token identifier about the game boardare determined according to movement tables stored in the game memory.Each of the movement tables correspond to one of the stations of thegame board and define a set of possible movement outcomes from thatstation. After identifying the position (station) of the tokenidentifier on the game board, the processor consults the movement tablecorresponding to that position to select a movement outcome. Then, theprocessor moves the token a number of steps on the game boardcorresponding to the selected movement outcome.

[0009] In accordance with still yet another aspect of the presentinvention, there is provided a feature in which escalating bonuses areawarded for reaching a designated bonus square on the game board. Thegaming machine includes a processor operable to execute a game programdefining a plurality of stations about a game board traversable by atoken identifier, one of the stations being designated as a bonusstation. As the token identifier is advanced along the game board,payoff(s) are made to the player when the token identifier reaches thebonus station, the payoffs escalating in value each successive time thetoken identifier reaches the bonus station.

[0010] In accordance with a still further aspect of the presentinvention, there is provided a feature in which bonuses are awarded forcompleting groups of stations (e.g., color groups) on the game board.The gaming machine includes a processor operable to execute a gameprogram defining a plurality of stations about a game board traversableby a token identifier, the plurality of stations having at least onediscernible subset defining a station group (e.g., a color group). Asthe token identifier is advanced along the game board, the processoridentifies respective landing stations occupied by the token identifier.If the landing station is a member of a station group, the processordesignates the landing station as a “completed” station. Then, theprocessor evaluates the station status of the other stations in thegroup. If each of the other stations in the group are also completed,the processor designates the group as a completed group and provides areward to the player, which might comprise an extra “spin” or play ofthe game, or might increase the award otherwise associated with thestation.

[0011] In accordance with a still yet further aspect of the presentinvention, there is provided a gaming machine with a processor operablein a basic mode and two bonus modes. In the basic mode, the processor isoperable to display a basic game outcome defining a symbol group. If thesymbol group includes a first bonus combination, the processor entersthe first bonus mode and, if the symbol group includes a second bonuscombination, the processor enters the second bonus mode. In the firstbonus mode, the processor sets up the first bonus game by defining aplurality of first bonus selection elements including fixed values andmultipliers. Then, the processor operates to select one of the selectionelements and the player is awarded a credit based on the value of theselected selection element. In the second bonus mode, the processoroperates to define a plurality of stations about a game boardtraversable by a token identifier. Then, the processor executes amovement of the token identifier to determine a landing station, and theplayer is awarded a credit based on the value of the landing station.

[0039] While the invention is susceptible to various modifications andalternative forms, specific embodiments have been shown by way ofexample in the drawings and will be described in detail herein. However,it should be understood that the invention is not intended to be limitedto the particular forms disclosed. Rather, the invention is to cover allmodifications, equivalents, and alternatives falling within the spiritand scope of the invention as defined by the appended claims.

DESCRIPTION OF SPECIFIC EMBODIMENTS

[0040] Turning now to the drawings and referring initially to FIG. 1,there is depicted a gaming machine 10 with a board game theme. In oneembodiment, the gaming machine 10 is operable to play a game entitledMONOPOLY ONCE AROUND™, based on the popular MONOPOLY™ board game.MONOPOLY is a registered trademark owned by and used with permission byHasbro, Inc. and Hasbro International, Inc., Pawtucket, R.I.Nevertheless, it will be appreciated that the gaming machine 10 may beimplemented with any of several other board game themes other thanMONOPOLY™.

[0041] The gaming machine 10 includes a video display 12 and a top boxdisplay 32. The video display 12 may comprise a dot matrix, CRT, LED,LCD, electro-luminescent display or generally any type of video displayknown in the art. The top box display 32 has a facing surface 60comprising a partially translucent material such as glass, plastic,Plexiglas or the like which includes an adaptation of a game board 62(e.g., MONOPOLY) displayed thereon. The game board 62 is backlit by anumber of lights 66 (not visible in FIG. 1) in the top box display 32. Apair of mechanical dice 64 are displayed near the top of the top boxdisplay 32.

[0042]FIG. 2 is a block diagram of a control system suitable foroperating the slot machine 10. Coin/credit detector 82 signals a CPU 70when a player has inserted a number of coins or played a number ofcredits. Then, after the player has activated a switch 84 (e.g., bypulling a lever or pushing a button), the CPU 70 operates to displayreels 14, 16, 18, 20 and 22 on the video screen 12. Then, the playeractivates one or more selected paylines 72-80 and presses the “SpinReels” button 36 or “Max Bet Spin” button 37 to “spin” the reels, aswill be described in greater detail in relation to FIG. 4. The CPU 70randomly selects a game outcome and causes the video display 12 todisplay indicia (e.g., symbols on reels 14, 16, 18, 20 and 22)corresponding to the pre-selected game outcome. In one embodiment, thesymbols displayed on the reels define the basic game outcome.

[0043] A system memory 86 stores control software, operationalinstructions and data associated with the gaming machine 10. In oneembodiment, the memory 86 comprises a separate read-only memory (ROM)and battery-backed random-access memory (RAM). However, it will beappreciated that the memory 86 may be implemented on any of severalalternative types of memory structures or may be implemented on a singlememory structure. A payoff mechanism 88 is operable in response toinstructions from the CPU 70 to award a payoff of coins or credits tothe player in response to certain winning combinations stored in memory86. As will be described in detail hereinafter, the payoff amountscorresponding to certain combinations is predetermined according to apay table stored in system memory 86. A separate I/O controller 71coupled to the CPU 70 operates the mechanical dice 64 and top box lights66.

[0044] The gaming machine 10 is operable to play a “basic” game and asecondary or “bonus” game. The basic game is implemented on the videodisplay 12 on five video simulated spinning reels, 14, 16, 18, 20 and 22(hereinafter “reels”) with nine paylines 72-80, as best observed in FIG.4. Generally, game play is initiated by inserting a number of coins orplaying a number of credits, causing the CPU 70 (FIG. 2) to activate anumber of paylines corresponding to the number of coins or creditsplayed. After activation of the paylines, the reels 14, 16, 18, 20 and22 are set in motion by either pulling a lever (not shown), pressing apush button, or touching a touch screen “key” on the video display 12.

[0045] In the embodiment of FIG. 4, each of the paylines 72-80 extendthrough one symbol on each of the five reels 14, 16, 18, 20 and 22.Payline 72 starts at the upper left symbol (e.g., “DOG”) on reel 14,extends through the center symbol (e.g., “DICE”) on reel 16, the lowersymbol (e.g., “CHANCE”) on reel 18, the center symbol (e.g., “DICE”) onreel 20 and terminates at the top symbol (e.g., “ELECTRIC CO.,”hereinafter “LIGHT”) on reel 22. Payline 73 starts at the upper leftsymbol (e.g., “DOG”) on reel 14, extends through the center symbol(e.g., “DICE”) on reel 16, the upper symbol (e.g., “SHOE”) on reel 18,the center symbol (e.g., “DICE”) on reel 20 and terminates at the topsymbol (e.g., “LIGHT”) on reel 22. Payline 74 extends through the topsymbol on each reel (e.g., “DOG” on reel 14, “COMMUNITY CHEST,”hereinafter “CHEST” on reel 16, “SHOE” on reel 18, “CAR” on reel 20 and“LIGHT” on reel 22.) Payline 75 starts at the center symbol (e.g., “FREEPARKING,” hereinafter “PARK”) on reel 14, extends through the lowersymbol (e.g., “SHOE”) on reel 16, the center symbol (e.g., “RING”) onreel 18, the lower symbol (e.g., “RICH UNCLE PENNYBAGS,” hereinafter“PENNY”) on reel 20 and terminates at the center symbol (e.g., “DOG”) onreel 22. Payline 76 extends through the center symbol on each reel(e.g., “PARK” on reel 14, “DICE” on reel 16, “RING” on reel 18, “DICE”on reel 20 and “DOG” on reel 22.) Payline 77 starts at the center symbol(e.g., “PARK”) on reel 14, extends through the upper symbol (e.g.,“CHEST”) on reel 16, the center symbol (e.g., “RING”) on reel 18, theupper symbol (e.g., “CAR”) on reel 20 and terminates at the centersymbol (e.g., “DOG”) on reel 22. Payline 78 extends through the lowersymbol on each reel (e.g., “TRAIN” on reel 14, “SHOE” on reel 16,“CHANCE” on reel 18, “PENNY” on reel 20 and “DICE” on reel 22.) Payline79 starts at the lower symbol (e.g., “TRAIN”) on reel 14, extendsthrough the center symbol (e.g., “DICE”) on reel 16, the lower symbol(e.g., “CHANCE”) on reel 18, the center symbol (e.g., “DICE”) on reel 20and terminates at the lower symbol (e.g., “DICE”) on reel 22. Payline 80starts at the lower symbol (e.g., “TRAIN”) on reel 14, extends throughthe center symbol (e.g., “DICE”) on reel 16, the upper symbol (e.g.,“SHOE”) on reel 18, the center symbol (e.g., “DICE”) on reel 20 andterminates at the lower symbol (e.g., “DICE”) on reel 22.

[0046] In one embodiment, the player selects the number of paylines(between one and nine) to play by pressing one of the five buttons inthe top row 28 or by using the “Select Lines” key 34 on the videodisplay 12. The player then chooses one of the five buttons in thebottom row 30 that correspond to the number of coins or credits to beton each of the nine paylines. Selecting one of the buttons in the bottomrow 30 sets the five video reels, 14, 16, 18, 20 and 22 in “motion”. Asan alternative, the player may touch the “Bet Per Line” key 35 on thevideo display 12 until the desired bet is displayed and then touch the“Spin Reels” key 36 on the video display 12 to begin the game. Asanother alternative, if the player wishes to bet the maximum amount oflines and the maximum bet per line, the player may touch the “Max BetSpin” key 37 on the video display 12 to begin the game. In oneembodiment, the game can be set for a maximum bet of 5 or 10 credits oneach payline for a maximum total bet of 45 or 90 credits per game. TheCPU 70 assigns an equal amount of credits bet for each payline and thenspins all five reels 14, 16, 18, 20 and 22.

[0047] The CPU 70 uses a random number generator (not shown) to select agame outcome (e.g., “basic” game outcome) corresponding to a particularset of reel “stop positions”. The CPU 70 then causes each of the videoreels 14, 16, 18, 20 and 22 to stop at a preselected stop position.Video symbols (see FIG. 4) are displayed on the reels 14, 16, 18, 20 and22 to graphically illustrate the reel stop position and indicate whetherthe stop position of the reels represents a winning game outcome.Winning “basic” game outcomes (e.g., symbol combinations resulting inpayment of coins or credits) are identifiable by a pay table (see TableA-1). In one embodiment, the pay table is affixed to the machine 10and/or displayed by the video display 12 in response to a command by theplayer (e.g., by pressing the “PAY TABLE” button 45). The pay tableenables the player to view the winning combinations and their associatedpayoff amounts. If the displayed symbols stop in a winning combination,the game awards the player the award corresponding to the award in thepay table for that combination multiplied by the amount of credits beton the winning payline.

[0048] Table A-1 is a pay table identifying various winning combinationsof symbols in the MONOPOLY ONCE AROUND basic game and their mathematicalprobabilities and expected values. The various symbols used in theMONOPOLY ONCE AROUND basic game include: “RICH UNCLE PENNYBAGS”(“PENNY”), “DICE,” “CAR,” “DOG,” “SHOE,” “RING,” “TRAIN,” “PARK,”“LIGHT,” “CHEST” and “CHANCE.” The “WIN COMBINATIONS” column identifiesthe various win combinations which may occur by symbols stopping on anactive payline. Generally, winning combinations require that at leasttwo of five corresponding symbols be displayed, left to right, startingon reel 14 (designated “R #1” in Table A-1) on an active payline. Forexample, two “PENNY” symbols displayed on adjacent reels 14 (“R #1”) and16 would be a winning combination. The “ANY TOKEN” combination issatisfied by any combination of three or more “CAR,” “DOG” and “SHOE”symbols stopping on an active payline, left to right, starting on reel14 (“R #1”). For example, a “DOG” symbol on reel 14 (“R #1”), followedby a “SHOE” symbol on reel 16 (“R #2”) and another “DOG” symbol on reel18 (“R #3”) would be a winning “ANY TOKEN” combination.

[0049] In one embodiment, the “PENNY” symbol acts as a wildcard for the“RING,” “TRAIN,” and “PARK” symbol combinations. Thus, for example, thecombination of “RING,” “PENNY” and “RING” on adjacent reels 14 (“R #1”),16 (“R #2”) and 18 (“R #3”) is a winning combination.

[0050] The “SCATTERED PAYS” column identifies the various wincombinations which may occur by symbols which are not necessarilyaligned with an active payline. A winning combination of the scatter-paytype occurs when scatter-pay symbols are displayed, in any position, onthe appropriate reels. In the MONOPOLY ONCE AROUND basic game, the“CHEST” and “CHANCE” symbols are scatter-pay symbols and winningcombinations occur when three or more of these symbols are displayed onconsecutive and adjacent interchangeable reels. For example, three“CHEST” symbols displayed on adjacent reels 16 (“R #2”), 18 (“R #3”) and20 (“R #4”), is a winning scatter-pay combination in the MONOPOLY ONCEAROUND™ game.

[0051] The “# OF HITS” column of Table A-1 identifies, for each winningcombination, the product of the number of symbols on each reelsupporting the combination. For example, consider the combination offive “PENNY” symbols. This combination is the highest value combinationin the MONOPOLY ONCE AROUND™ basic game because there are relatively few“PENNY” symbols on each reel and, consequently, the probability ofhitting a “PENNY” symbol on each reel is very low. Specifically, in theembodiment of Table A-1, there is one “PENNY” symbol on reel 14 (“R#1”), two “PENNY” symbols on reel 16 (“R #2”), two “PENNY” symbols onreel 18 (“R #3”), two “PENNY” symbols on reel 20 (“R #4”) and four“PENNY” symbols on reel 22 (“R #5”). Thus, the “# OF HITS” for thecombination of five consecutive “PENNY” symbols is 32 (i.e., 1×2×2×2×4).

[0052] The “PAY” column of Table A-1 identifies the amount of coin(s) orcredit(s) awarded for the various winning combinations in the basicgame, per unit wagered. Thus, for example, the “PENNY,” “PENNY”combination appearing on reels 14, 16 (“R #1, R #2”) will pay 20 coinsor credits with one coin played; that same combination will pay 100coins or credits with five coins played.

[0053] The “TOTAL” column of Table A-1 lists, for each winningcombination, the product of the “# OF HITS” value and the “PAY” value.The five “PENNY” combination, for example, having 32 hits each paying20,000 coins or credits, has a “TOTAL” value of 640,000.

[0054] In one embodiment, each of the reels 14, 16, 18, 20 and 22 have48 symbol positions, thus the odds of hitting each unique combinationrelative to a single active payline is one in about 254 million (i.e.,1÷(48)⁵). The “PROB” column identifies the probability of hitting thevarious winning combinations in a single spin. For example, there areonly 32 symbol combinations out of about 250 million symbol combinationsthat will result in the combination of five consecutive “PENNY” symbols.Thus, the probability of hitting that combination is 32÷254 million orabout 1.25×10⁻⁷.

[0055] The “EV” column of Table A-1 identifies the expected value of thevarious winning combinations, which is computed as the product of the“PAY” and “PROB” values. Thus, for the five “PENNY” combination, theexpected value is 0.0025 (20,000×1.25×10⁻⁷). The payout rate of thebasic game, identified at the bottom of the “EV” column, is computed bysumming each of the expected values. In the embodiment of Table A-1, thepayout rate of the basic game is 73.60%

[0056] The Bonus Game

[0057] The bonus game is triggered when a special “start-bonus” outcomeoccurs in the basic game. In the MONOPOLY ONCE AROUND™ game, a winningcombination of three or more “DICE” symbols in the basic game representsa “start-bonus” outcome which causes the CPU 70 to execute a gamecontrol instruction which enters the bonus game. In one embodiment, thebonus game has a board-game (e.g., MONOPOLY) theme and is implemented onthe top box game board 62 and video display 12. The board game defines aplurality of stations or squares about a game board traversable by agame token, or token “identifier” indicating the position of a token, orplayer. For example, a token “identifier” comprises in one embodiment anilluminated station of the top box game board 62 indicating the positionof a token, or player otherwise not displayed on the top box game board62. Hereinafter, references to displaying the position of a token, orplayer, shall be understood to mean the display of either an actual gametoken or a token identifier on a game board or portion thereof.

[0058] Upon initially entering the bonus game, the CPU 70 operates toreplace the display of reels 14, 16, 18, 20, 22 on video display 12 witha token selection screen (FIG. 5) offering a selection of board gametokens 40. In the MONOPOLY ONCE AROUND™ game, the token selection screendisplays an animated Rich Uncle Pennybags symbol 38 above a selection ofMONOPOLY tokens 40 (e.g., “CAR,” “DOG,” “HORSE,” “SHOE” and “HAT”), andthe player is prompted to select one of the game tokens 40. In oneembodiment, the video display 12 comprises a touch-screen display andthe selection of a game token 40 is accomplished by touching the desiredtoken on the display 12. It will be appreciated, however, that any ofseveral known player control devices may be used to implement theselection of a token 40. In another embodiment, the player scrollsthrough the tokens 40 and selects a particular token by depressing adesignated “select” button on the gaming machine 10 when the desiredtoken 40 is highlighted. Scrolling through the tokens 40 prior to theselection of the desired token may also be accomplished automaticallyaccording to the game program or may be controlled by the playerpressing various buttons. Once the player selects a token 40, the CPU 70operates to display a portion of the game board on the video display 12with the selected token on a starting station of the game board. The CPU70 also signals I/O controller 71 to illuminate the starting station onthe top box game board 62. For example, in the MONOPOLY ONCE AROUND™game, the starting station is the ‘GO’ square. The CPU 70 operates todisplay the selected MONOPOLY token on the GO square of a scrollingvideo MONOPOLY board on the video display 12, and also signals I/Ocontroller 71 to illuminate the GO square on the top box MONOPOLY board62.

[0059] Next, in one embodiment, the CPU 70 selects an integer movementvalue defining a number of stations or steps which the token is to bemoved from the GO square. In one embodiment, the integer movement valueis selected from a plurality of movement values corresponding to the sumof two dice. In this case, the selection of the movement value mightcomprise selecting two integer values, each corresponding to a possibleoutcome of one of the dies, then summing the integer values. Forexample, in one embodiment, the CPU 70 selects a first integer value,from one to six, corresponding to the faces of a six-sided first die,then selects a second integer value, from one to six, corresponding tothe faces of a six-sided second die. The CPU 70 sums the two values todefine the integer movement value, comprising a number from two totwelve. Alternatively, the CPU 70 might select an integer movement valuefrom two to twelve without selecting and summing intermediate values.

[0060] In one embodiment, the player “rolls” a pair of dice by touchinga “Roll Dice” key 41 or “Auto Roll” key 42 on the video display 12. Theoutcome of each roll (e.g., the integer movement value) is selected bythe CPU 70 which then issues game control instructions to displayindicia of the pre-determined “roll.” In one embodiment, the displayedindicia comprise mechanical dice 64 and a pair of “video” dice 43 on thevideo display 12 (FIG. 6). In one embodiment, the mechanical dice 64 aredriven by I/O controller 71, in response to game control instructionsfrom the CPU 70, to mechanically rotate and then stop to reveal thepredetermined outcome of the roll. The video dice 43 similarly “rotate”and then stop to reveal the predetermined roll in response toinstructions from the CPU 70. The outcome of the roll of dice 43 (FIG.6) and 64 (FIG. 1) determines how many spaces the token will be movedfrom its previous position on the game board. On the top box display 32,movement is illustrated by the illumination, in step-wise fashion, ofthe appropriate stations (squares) on the game board 62 (e.g., MONOPOLYboard) from the previous position to the position determined by the rollof dice. On the video display 12, movement is illustrated by theselected game token 40 (e.g., “SHOE” in FIG. 6) moving, one space at atime, a corresponding number of spaces on a scrolling portion of thegame board.

[0061] In one embodiment, when the token 40 stops moving for each roll,an animated character icon (e.g., Rich Uncle Pennybags, in the MONOPOLYONCE AROUND™ game) announces the name of the station (square) landed onby the token 40. The player is awarded the amount indicated on thestation multiplied by the line bet. In one embodiment, the player mightbe awarded an additional amount resulting from a side bet, if any,associated with the station (which will be described in relation to FIG.7). In one embodiment, the bonus game continues with consecutive rollsof the dice, with the player collecting various amounts corresponding tothe landing stations determined by the rolls of dice, until the player'stoken has completed one trip around the game board. If the rolls areinitiated by pressing the “Roll Dice” key 41, the game will pausebetween rolls until the player touches the key 41 or 42. If the rollsare initiated by the “Auto Roll” key 42, the CPU 70 causes the dice toroll automatically after a small delay following the previous roll.

[0062] In the MONOPOLY ONCE AROUND™ game, if the game token 40 lands ona “Chance” or “Community Chest” station (square) during the bonus round,the CPU 70 triggers an animation on video display 12 which shows the topcard of a pile of cards flipping up to reveal the “Chance” or “CommunityChest” outcomes. The art on the cards resembles the cards in an actualMONOPOLY™ game. Generally, the “Chance” and “Community Chest” outcomescomprise awards of fixed coin values (e.g., “BANK ERROR IN YOUR FAVOR,$100), or they can move the player to a new space (e.g., GO BACK ONESPACE). If the player is moved to a property, the movement is indicatedon the top box board 62 and the video display 12. The possible outcomesof the “Chance” and “Community Chest” squares in one embodiment of theMONOPOLY ONCE AROUND™ bonus game is shown in Table A-2, below.

[0063] In one embodiment of the MONOPOLY ONCE AROUND™ game, if the gametoken 40 lands on station(s) other than “Chance” or “Community Chest,”the CPU 70 causes the player to be awarded an amount of creditscorresponding to the product of the coins or credits wagered per line inthe basic game and a multiplier value associated with the respectivestation(s). Four of the stations (e.g., “INCOME TAX,” “IN JAIL,” “GO TOJAIL” and “LUXURY TAX”) have zero value in the bonus game, that is, theyare associated with zero multiplier amounts. All other stations havepositive integer multiplier values which generally increase as the tokenprogresses farther along the board. The multiplier values associatedwith the respective stations are shown in FIG. 3 and Table A-3, below.TABLE A-3 MONOPOLY BONUS SQUARES MONOPOLY BONUS SNAKE Cost/ HouseW/Snake SQUARE MULT PROB EYES Exp Pay Exp Value House Pay Eyes EVMediterranean Ave. 4 0.0028 0.002778 0.01 0.001% 5 75 1750 97.22%Community Chest 29.10 0.0278% 0.027778 0.81 0.082% Baltic Avenue 50.0556 0.00008 0.28 0.028% 5 75 2500 87.19% Income Tax 0 0.0843 0.000770.00 0.000% Reading Railroad 10 0.1144 0.00155 1.14 0.116% OrientalAvenue 10 0.1469 0.00234 1.47 0.149% 5 25 400 91.03% Chance 34.9 0.18260.00318 6.37 0.646% Vermont Avenue 10 0.1669 0.00408 1.67 0.169% 5 25150 93.63% Connecticut Avenue 12 0.1560 0.00507 1.87 0.190% 5 25 17593.21% In Jail 0 0.1482 0.00463 0.00 0.000% St. Charles Place 15 0.14170.00433 2.13 0.215% 10 50 600 94.67% Electric Company 12 0.1346 0.004121.62 0.164% States Avenue 15 0.1251 0.00394 1.88 0.190% 10 50 800 92.06%Virginia Avenue 18 0.1389 0.00374 2.50 0.253% 10 50 700 93.76%Pennsylvania Railroad 10 0.1462 0.00347 1.46 0.148% St. James Place 200.1488 0.00386 2.98 0.301% 10 50 500 91.74% Community Chest 32.33 0.14830.00406 4.80 0.486% Tennessee Avenue 20 0.1461 0.00413 2.92 0.296% 10 50500 91.64% NewYork Avenue 22 0.1433 0.00412 3.15 0.319% 10 50 600 94.30%Free Parking 10 0.1412 0.00406 4.80 0.486% Kentucky Avenue 25 0.14110.00398 3.53 0.357% 15 75 900 92.46% Chance 34.9 0.1419 0.00392 4.950.502% Indiana Avenue 25 0.1429 0.00392 3.57 0.362% 15 75 900 93.01%Illinois Avenue 28 0.1436 0.00394 4.02 0.407% 15 75 900 93.51% B & ORailroad 10 0.1440 0.00397 1.44 0.146% Atlantic Avenue 30 0.1441 0.003994.32 0.438% 15 75 900 93.98% Ventnor Avenue 30 0.1436 0.00400 4.310.436% 15 75 900 93.81% Water Works 12 0.1432 0.00400 1.72 0.174% MarvinGardens 35 0.1429 0.00399 5.00 0.507% 15 75 900 93.40% Go to Jail 00.1429 0.00298 0.00 0.000% Pacific Avenue 50 0.1430 0.00397 7.15 0.724%20 100 1200 93.36% North Carolina Avenue 50 0.1432 0.00397 7.16 0.725520 100 1200 93.45% Community Chest 32.33 0.1434 0.00397 4.64 0.469%Pennsylvania Avenue 60 0.1434 0.00398 8.60 0.871% 20 100 1200 93.58%Short Line Railroad 10 0.1434 0.00398 1.43 0.1455 Chance 34.9 0.14330.00398 5.00 0.506% Park Place 100 0.1432 0.00398 14.32 1.451% 20 1001200 93.52% Luxury Tax 0 0.1432 0.00398 0.00 0.000% Boardwalk 300 0.14320.00398 42.96 4.351% 20 100 1200 93.48% Go 5 1.0000 0.00298 5.00 0.506%Total Spaces 39 6.2192 Average 29.78 0.16 Expected Value 167.60 16.97%

[0064] In one embodiment, the bonus game gives the player theopportunity to make side bets, apart from the coins or credits wageredin the basic game, on the stations of the game board which the playerpredicts will be landed on during the bonus game. The increments of theside bets which may be made on the various stations may be variedaccording to the game program. For example, in the MONOPOLY ONCE AROUND™bonus game, the player has the opportunity to “build” houses (make sidebets) on the properties of the MONOPOLY board which the player predictswill be landed on during the bonus game. The amount of the side betcorresponds to the “cost” of the houses built on the various properties,which generally varies according to the property selected.

[0065] If the player wishes to build house(s), the player touches the“Build Houses” key 46 on the video display 12 (FIG. 5) which appears atthe beginning of the bonus round. If the “Build Houses” key 46 isselected, the CPU 70 operates to display a “Build Houses” screen (FIG.7) on the video display. In one embodiment, the video display 12comprises a touch-screen display and the player bets (builds houses) ona property by touching the desired property. It will be appreciated,however, that any of several alternative player control devices may beused to implement the selection and building of houses.

[0066] After selection of a property, the CPU 70 operates to display aproperty deed 54 corresponding to the selected property on the videodisplay 12. In FIG. 7, the property deed shown on the video display 54is “Baltic Avenue,” thus indicating that the player has elected to buildhouses on Baltic Avenue. More specifically, the player has identifiedthe “Baltic Avenue” station as a predicted landing position of thetoken, to be determined by execution of the game program. The playerbuilds houses on the selected property by touching the property again,by touching the deed 54, or by touching the “Build Houses” key 46. Up tofive bets (houses) may be placed on each property. In one embodiment,the houses on the bottom side of the MONOPOLY™ board (from MediterraneanAve. to Connecticut Ave.) cost 5 credits each, the houses on the leftside of the board (St. Charles Place to New York Ave.) cost 10 creditseach, the houses on the top side of the board (Kentucky Ave. to MarvinGardens) cost 15 credits each and the houses on the right side of theboard (Pacific Ave. to Boardwalk) cost 20 credits each.

[0067] The cost of the houses are subtracted from the credits previouslyearned or paid into the machine by the player. In one embodiment, theplayer may insert coins or bills into the machine 10 at any time duringdisplay of the “Build Houses” screen as desired to increase the creditsavailable for building houses. If the player, having selected a propertyand placed house(s) on the property, wants to clear the house(s) on theselected property, the player touches a “Clear Property” key 48 on thedisplay 12. If the player wants to clear houses (side bets) placed onthe entire board, the player touches a “Clear All Houses” key 50 on thedisplay 12.

[0068] In one embodiment, the video display 12 displays a number ofhouse and hotel icons corresponding to the number of houses built oneach selected property. In FIG. 7, for example, the video display 12shows four green house icons and a red hotel icon adjacent to the BalticAvenue property deed, thus indicating that the player has placed fivebets on Baltic Avenue. The four house icons represent the first fourbets and the hotel icon represents the fifth bet placed on BalticAvenue. The displayed property deed 54 identifies the cost per house(e.g., 5 credits for Baltic Avenue) and the pay value of landing on theproperty (e.g., 125 credits for Baltic Avenue, with five houses).

[0069] In one embodiment, the game program defines a target integermovement value and a bonus is awarded to the player if the player“rolls” the target integer movement value to land on the selectedproperty. The bonus comprises a higher value award, greater than theaward which would otherwise be awarded by landing on the selectedproperty. In the illustrated embodiment, the target integer movementvalue is two, corresponding to a roll of “Snake Eyes” (double ones). Thedisplayed property deed 54 indicates the pay value of the “Snake Eyes”bonus, 2000 credits for Baltic Avenue (with five houses). The cost perhouse, pay value per house and Snake Eyes bonus value per house for thevarious properties in one embodiment of the MONOPOLY ONCE AROUND™ gameis identifed in Table A-3.

[0070] In one embodiment, a “Help” key 44 is displayed on the “BuildHouses” screen. If touched by the player, the “Help” key 44 allows theplayer to access various information and instructions associated withthe build houses feature. For example, in one embodiment, theinformation associated with the “Help” key 44 may allow the player todetermine how much the Snake Eyes bonus is worth for the variousproperties.

[0071] After the player has placed the desired number of side bets, theplayer touches a “Return to Game” key 52 on the display 12, causing theCPU 70 to replace the “Build Houses” screen with a display of theMONOPOLY board screen (FIG. 6) with the token starting on the GO square.Then, the player presses the “Roll Dice” button 41 or “Auto Roll” button42 to roll the dice and commence the bonus game.

[0072] Then, the CPU 70 executes a game program, selecting integermovement values corresponding to a roll of dice to advance the gametoken, or token identifier along the game board. The landing station(s)of the token identifier determined by execution of the game programdefine “actual” or “true” position(s) of the token identifier, asopposed to the predicted positions selected via the “Build Houses”screen. After each “roll,” the CPU 70 compares the true position to thepredicted position(s) and, if the true position matches any of thepredicted position(s), the player is paid an amount of coins or credits,as appropriate, corresponding to the cost of building the house(s) onthat property. In one embodiment, the amount paid upon landing on animproved property is five times the cost of building houses on thatproperty. The “Build Houses” award(s), if any, are supplemental to theawards given as a result of landing on the properties in the regularbonus game.

[0073] The award of coin(s) or credit(s) for the “Build Houses” featureor the regular bonus game may occur immediately upon the token 40landing on a particular property or may be deferred until completion ofthe bonus game. In one embodiment, the animated Rich Uncle Pennybagswill celebrate on the display 12 during all large bonus awards. Afterthe bonus game is complete, the bonus screen will fade and the videoreels screen will then be displayed on the display 12 so the player mayresuming playing the basic game.

[0074] Now turning to FIG. 8, there is depicted another gaming machine110 with a board game theme. In one embodiment, the gaming machine 110is operable to play a game entitled MONOPOLY REEL ESTATE™, based on theMONOPOLY™ board game. MONOPOLY™ is a registered trademark owned by andused with permission by Hasbro, Inc. and Hasbro International, Inc.,Pawtucket, R.I. Alternatively, the gaming machine 110 may be implementedwith any of several other board game themes other than MONOPOLY™.

[0075] The gaming machine 110 includes a video display 112 and a top boxdisplay 132. The video display 112 may comprise a dot matrix, CRT, LED,LCD, electro-luminescent display or generally any type of video displayknown in the art. The top box display 132 has a facing surface 160comprising a partially translucent material such as glass, plastic,Plexiglas or the like which includes an adaptation of a game board 162(e.g., MONOPOLY) displayed thereon. The game board 162 is backlit by anumber of lights 166 (not visible in FIG. 1) in the top box display 132.

[0076]FIG. 9 is a block diagram of a control system suitable foroperating the slot machine 110 of FIG. 8. Coin/credit detector 182signals a CPU 170 when a player has inserted a number of coins or playeda number of credits. Then, after the player has activated a switch 184(e.g., by pulling a lever or pushing a button), the CPU 170 operates todisplay reels 114, 116, 118, 120 and 122 (see FIG. 11) on the videoscreen 112. The player activates one or more selected paylines 172, 174,176, 178, 180 and presses the “Spin Reels” button 136 or “Max Bet Spin”button 137 to “spin” the reels, as will be described in relation to FIG.11. The CPU 170 randomly selects a game outcome and causes the videodisplay 112 to display indicia (e.g., symbols on reels 114, 116, 118,120 and 122) corresponding to the pre-selected game outcome. In oneembodiment, the symbols displayed on the reels define the basic gameoutcome.

[0077] A system memory 186 stores control software, operationalinstructions and data associated with the gaming machine 110. In oneembodiment, the memory 186 comprises a separate read-only memory (ROM)and battery-backed random-access memory (RAM). However, it will beappreciated that the memory 186 may be implemented on any of severalalternative types of memory structures or may be implemented on a singlememory structure. A payoff mechanism 188 is operable in response toinstructions from the CPU 170 to award a payoff of coins or credits tothe player in response to certain winning combinations stored in memory186. As will be described in detail hereinafter, the payoff amountscorresponding to certain combinations is predetermined according to apay table stored in system memory 186. A separate I/O controller 171coupled to the CPU 170 operates the top box lights 266.

[0078] The gaming machine 110 is operable to play a basic game and abonus game. The basic game is implemented on the video display 112 onfive video simulated spinning reels, 114, 116, 118, 120 and 122(hereinafter “reels”) with five paylines 172, 174, 176, 178 and 180, asbest observed in FIG. 11. Generally, game play is initiated by insertinga number of coins or playing a number of credits, causing the CPU 170(FIG. 9) to activate a number of paylines corresponding to the number ofcoins or credits played. After activation of the paylines, the reels114, 116, 118, 120 and 122 are set in motion by either pulling a lever(not shown), pressing a push button, or touching a touch screen “key” onthe video display 112.

[0079] In the embodiment of FIG. 11, each of the paylines 172, 174, 176,178 and 180 extend through one symbol on each of the five reels 114,116, 118, 120 and 122. Payline 172 starts at the upper left symbol(e.g., “TRAIN”) on reel 114, extends through the center symbol (e.g.,“WATER WORKS,” hereinafter “WATER”) on reel 116, the lower symbol (e.g.,“WATER”) on reel 118, the center symbol (e.g., “TRAIN”) on reel 120 andterminates at the top symbol (e.g., “HAT”) on reel 122. Payline 174extends through the top symbol on each reel (e.g., “TRAIN” on reel 114,“ELECTRIC COMPANY,” hereinafter “LIGHT” on reel 116, “COMMUNITY CHEST,”hereinafter “CHEST” on reel 118, “RICH UNCLE PENNYBAGS,” hereinafter“PENNY” on reel 120 and “HAT” on reel 122.) Payline 176 extends throughthe center symbol on each reel (e.g., “FREE PARKING,” hereinafter“PARKING” on reel 114, “WATER” on reel 116, “DOG” on reel 118, “TRAIN”on reel 120 and “LIGHT” on reel 122.) Payline 178 extends through thelower symbol on each reel (e.g., “PENNY” on reel 114, “CHANCE” on reel116, “WATER” on reel 118, “CAR” on reel 120 and “PARKING” on reel 122.)Payline 180 starts at the lower symbol (e.g., “PENNY”) on reel 114,extends through the center symbol (e.g., “WATER”) on reel 116, the uppersymbol (e.g., “CHEST”) on reel 118, the center symbol (e.g., “TRAIN”) onreel 120 and terminates at the lower symbol (e.g., “PARKING”) on reel122.

[0080] In one embodiment, the player selects the number of paylines(between one and five) to play by pressing one of the five buttons inthe top row 128 or by using the “Select Lines” key 134 on the videodisplay 112. The player then chooses one of the five buttons in thebottom row 130 that correspond to the number of coins or credits to beton each of the five paylines. Selecting one of the buttons in the bottomrow 130 sets the five video reels, 114, 116, 118, 120 and 122 in“motion”. As an alternative, the player may touch the “Bet Per Line” key135 on the video display 112 until the desired bet is displayed and thentouch the “Spin Reels” key 136 on the video display 112 to begin thegame. As another alternative, if the player wishes to bet the maximumamount of lines and the maximum bet per line, the player may touch the“Max Bet Spin” key 137 on the video display 112 to begin the game. Inone embodiment, the game can be set for a maximum bet of 5, 9 or 18credits on each payline for a maximum total bet of 25, 45 or 90 creditsper game. The CPU 70 assigns an equal amount of credits bet for eachpayline and then spins all five reels 114, 116, 118, 120 and 122.

[0081] The CPU 170 uses a random number generator (not shown) to selecta game outcome (e.g., “basic” game outcome) corresponding to aparticular set of reel “stop positions”. The CPU 170 then causes each ofthe video reels 114, 116, 118, 120 and 122 to stop at a preselected stopposition. Video symbols (see FIG. 11) are displayed on the reels 114,116, 118, 120 and 122 to graphically illustrate the reel stop positionand indicate whether the stop position of the reels represents a winninggame outcome. Winning “basic” game outcomes (e.g., symbol combinationsresulting in payment of coins or credits) are identifiable by a paytable (see Table B-1). In one embodiment, the pay table is affixed tothe machine 110 and/or displayed by the video display 112 in response toa command by the player (e.g., by pressing the “PAY TABLE” button 145).The pay table enables the player to view the winning combinations andtheir associated payoff amounts. If the displayed symbols stop in awinning combination, the game awards the player the award correspondingto the award in the pay table for that combination multiplied by theamount of credits bet on the winning payline.

[0082] Table B-1 is a pay table identifying various winning combinationsof symbols in the MONOPOLY REEL ESTATE™ basic game and theirmathematical probabilities and expected values. The various symbols usedin the MONOPOLY REEL ESTATE™ basic game include: “RICH UNCLE PENNYBAGS”(“PENNY”), “CAR,” “HAT,” “DOG,” “TRAIN,” “PARKING,” “WATER,” “LIGHT,”“CHEST” and “CHANCE.”

[0083] The “WIN COMBINATIONS” column identifies the various wincombinations which may occur by symbols stopping on an active payline.Generally, winning combinations can occur when one to five correspondingsymbols are displayed, left to right, starting on reel 114 (designated“R #1” in Table B-1) on an active payline. For example, one “PENNY”symbol displayed on reel 114 is a winning outcome, as is two “PENNY”symbols displayed on adjacent reels 114 (“R #1”) and 116 (“R #2”).

[0084] In one embodiment, the “PENNY” symbol acts as a wildcard forcombinations of game tokens “CAR,” “HAT” and “DOG.” Thus, for example,the combination of “CAR,” “PENNY” and “CAR” on adjacent reels 114 (“R#1”), 116 (R #2) and 118 (R #3) is a winning combination.

[0085] The “SCATTERED PAYS” column identifies the various wincombinations which may occur by symbols which are not necessarilyaligned with an active payline. A winning combination of the scatter-paytype occurs when scatter-pay symbols are displayed, in any position, onthe appropriate reels. In the MONOPOLY REEL ESTATE basic game, the“CHEST” and “CHANCE” symbols are scatter-pay symbols and winningcombinations occur when three or more of these symbols are displayed onadjacent reels. For example, three “CHEST” symbols displayed on adjacentreels 116 (“R #2”), 118 (R #3) and 120 (R #4), is a winning scatter-paycombination in the MONOPOLY REEL ESTATE game.

[0086] The “# OF HITS” column of Table B-1 identifies, for each winningcombination, the product of the number of symbols on each reelsupporting the combination. For example, consider the combination offive “PENNY” symbols. This combination is the highest value combinationin the MONOPOLY REEL ESTATE™ basic game because there are relatively few“PENNY” symbols on each reel and, consequently, the probability ofhitting a “PENNY” symbol on each reel is very low. Specifically, in theembodiment of Table B-1, there is one “PENNY” symbol on each of reels114 (“R #1”), 116 (“R #2”), 118 (“R #3”), 120 (“R #4”) and 122 (“R #5”).Thus, the “# OF HITS” for the combination of five consecutive “PENNY”symbols is 1 (i.e., 1×1×1×1×1).

[0087] The “PAY” column of Table B-1 identifies the amount of coin(s) orcredit(s) awarded for the various winning combinations in the basicgame, per unit wagered. Thus, for example, the “PENNY,” “PENNY”combination appearing on reels 114, 116 (“R #1, R #2”) will pay 10 coinsor credits with one coin played; that same combination will pay 50 coinsor credits with five coins played.

[0088] The “TOTAL” column of Table B-1 lists, for each winningcombination, the product of the “# OF HITS” value and the “PAY” value.The five “PENNY” combination, for example, having 1 hit paying 10,000coins or credits, has a “TOTAL” value of 10,000. As another example, thefour “PENNY” combination, having 24 hits paying 1,000 coins or credits,has a “TOTAL” value of 24,000.

[0089] In one embodiment, each of the reels 114, 116, 118, 120 and 122have 26 symbol positions, thus the odds of hitting each uniquecombination relative to a single active payline is one in about 12million (i.e., 1÷(26)⁵). The “PROB” column identifies the probability ofhitting the various winning combinations in a single spin. For example,there is only 1 symbol combination out of about 12 million symbolcombinations that will result in the combination of five consecutive“PENNY” symbols. Thus, the probability of hitting that combination is1÷12 million or about 8.4×10⁻⁸.

[0090] The “EV” column of Table B-1 identifies the expected value of thevarious winning combinations, which is computed as the product of the“PAY” and “PROB” values. Thus, for the five “PENNY” combination, theexpected value is 0.08% (10,000×8.4×10⁻⁸). The payout rate of the basicgame, identified at the bottom of the “EV” column, is computed bysumming each of the expected values. In the embodiment of Table B-1, thepayout rate of the basic game is 74.6%

[0091] The Bonus Game

[0092] The bonus game is triggered when a special “start-bonus” outcomeoccurs in the basic game. In one embodiment of the MONOPOLY REEL ESTATE™game, the bonus game is triggered when three or more “CHEST” or “CHANCE”symbols are displayed in scatter-pay format on adjacent ones of thereels 114, 116, 118, 120 and 122. Alternatively, depending on the gameprogram, the bonus game might be triggered when the “CHEST” or “CHANCE”symbols are displayed on an active payline on the reels 114, 116, 118,120 and 122. The bonus game has a board-game (e.g., MONOPOLY) theme andis implemented on the top box game board 162 and video display 112.

[0093] Upon initially entering the bonus game, the CPU 170 operates toreplace the display of reels 114, 116, 118, 120, 122 on video display112 with a token selection screen (FIG. 12) offering a selection ofboard game tokens 140. In the MONOPOLY REEL ESTATE game, the tokenselection screen displays an animated Rich Uncle Pennybags symbol 138above a selection of MONOPOLY tokens 140 (e.g., “CAR,” “DOG,” “HORSE,”“SHOE” and “HAT”), and the player is prompted to select one of the gametokens 140. In one embodiment, the video display 112 comprises atouch-screen display and the selection of a game token 140 isaccomplished by touching the desired token on the display 112. It willbe appreciated, however, that any of several known player controldevices may be used to implement the selection of a token 140. Inanother embodiment, the player scrolls through the tokens 140 andselects a particular token by depressing a designated “select” button onthe gaming machine 110 when the desired token 140 is highlighted.Scrolling through the tokens 140 prior to the selection of the desiredtoken may also be accomplished automatically according to the gameprogram or may be controlled by the player pressing various buttons.Once the player selects a token 140,

[0094] Once the player selects a token 140, the CPU 170 signals the I/Ocontroller 171 to illuminate a starting station on the top box gameboard 162 and then illuminate successive stations around the board instep-wise fashion, rapidly at first and then, after a couple ofrevolutions, slowing down and stopping on an indicated station.Generally, the indicated station is randomly determined by the CPU 170prior to the illumination of successive stations on the top box gameboard 162. At a certain point, as the light on the top box game board162 begins slowing down, the CPU 170 operates to generate acorresponding display on the video display 112, in which the selectedtoken 140 “moves” on a scrolling portion of the game board beforeultimately stopping on the indicated station. The movement of the gametoken 140 on the video display 112 corresponds exactly to theillumination of stations on the top box game board 162.

[0095] For example, in the MONOPOLY REEL ESTATE™ game, once the playerselects a token, the stations (squares) of the top box MONOPOLY board162 are illuminated in step-wise fashion, starting with the GO square.The illumination of stations starts rapidly, then slows down and stopsto reveal an indicated station of the MONOPOLY board. On thecorresponding video display 112 (FIG. 13), the selected MONOPOLY token140 (e.g., “HORSE”) is shown advancing on a scrolling MONOPOLY board andthen stopping on the indicated station (e.g., the “GO” square in FIG.13).

[0096] In one embodiment, when the token 140 “lands” on the indicatedstation, an animated character icon (e.g., Rich Uncle Pennybags, in theMONOPOLY REEL ESTATE™ game) announces the name of the indicated stationand the player is awarded an amount associated with the station. If thegame token 140 lands on a “Chance” or “Community Chest” square, the CPU170 triggers an animation on video display 112 which shows the top cardof a pile of cards flipping up to reveal the “Chance” or “CommunityChest” outcome. The art on the cards resembles the cards in an actualMONOPOLY™ game. Generally, the “Chance” and “Community Chest” outcomescomprise awards of fixed coin values (e.g., “LIFE INSURANCE MATURES,$12), or they move the player to a new space (e.g., ADVANCE TOBOARDWALK). If the player is moved to a property, the movement isindicated on the top box board 62 and the video display 12. The possibleoutcomes of the “Chance” and “Community Chest” squares in one embodimentof the MONOPOLY REEL ESTATE™ bonus game is shown in Table B-2, below.TABLE B-2 Chance and Community Chest Outcomes/Pay Values Community ChestPay Chance Pay Beauty Contest 3 Your Win 3rd Place in Dance 4 ContestLife Insurance Matures 12 Your Horse Wins the Derby 12 XMAS Fund Matures8 You Win State Lottery 25 You Inherit Money 15 Your Number Hits atRoulette 15 Wheel Income Tax Refund 9 Lawsuit in your Favor 12 BankError In Your 25 Find Lost Dog 3 Favor Receive For Services 6 Your Buildand Load Matures 10 From Sale of Stock You 10 Bank Pays You Dividend 8Get Grand Opera Opening 5 Sell Rare Painting at Auction 10 Advance toBoardwalk 50 Advance to Park Place 30 Average 14.30 Average 12.90

[0097] In one embodiment of the MONOPOLY REEL ESTATE™ game, if the gametoken 140 lands on station(s) other than “Chance” or “Community Chest,”the CPU 170 causes the player to be awarded an amount of creditscorresponding to the product of the coins or credits wagered in thebasic game and a multiplier value associated with the respectivestation(s). All of the stations have positive integer multiplier valueswhich generally increase as the token progresses farther along theboard. The multiplier values associated with the respective stations areshown in FIG. 10 and Table B-3, below.

[0098] The bonus game nominally consists of only one indicated outcome(“spin”) resulting in a single bonus award, after which the CPU 170returns to the basic game. In one embodiment, an animated Rich UnclePennybags will celebrate on the video display 112 during all large bonusawards. After the bonus game is complete, the CPU 170 causes the bonusscreen to fade and the video reels to be displayed so the player mayresume playing the basic game.

[0099] In one embodiment, certain of the stations of the game board 162have characteristics which identify them as members of a discerniblesubset or group of the stations. For example, in the MONOPOLY REELESTATE™ game, as in the actual MONOPOLY board game, the variousproperties of the game board are associated with color groups:Mediterranean Ave. and Baltic Ave. define a purple color group, OrientalAve, Vermont Ave. and Connecticut Ave. define a light blue color groupand so forth. In one embodiment, additional spins may be awarded by“completing” all the stations of a particular color group. Upon eachplay of the bonus game, if the token 140 lands on a station (e.g.,property square) that is part of a color group, the CPU 170 identifiesthe station as a “completed” station and stores the outcome of that spinin game memory. Then, in one embodiment, the CPU 170 causes the I/Ocontroller 171 to light an indicator light associated with that propertyon the game board 162, thereby indicating that the property is a“completed” property.

[0100] After each movement of the token, or token identifier, on thegame board 162, the CPU 170 assigns a “completed” status to the landingstation, as appropriate, then evaluates the status of the other stationsin the group. If the other stations in the group also have beencompleted, the CPU 170 identifies that group as a completed group andprovides a reward to the player. The reward might comprise an additionalbonus game “spin” or an enhanced payoff relative to the base value ofthe property landed on. For example, if the token lands on MediterraneanAve., which is a member of the purple color group, the CPU 170 assigns acompleted status to the Mediterranean Avenue station and then evaluatesthe status of the other purple station, Baltic Avenue. Continuing thepresent example, if Baltic Avenue were also “completed,” the CPU 170would identify the purple group as a completed group and reward theplayer as appropriate, with perhaps an additional bonus game “spin.”Alternatively or additionally, other incentives might be provided forcompleting color groups. For example, in one embodiment, if a player'stoken 140 lands on a property space that completes a color group, theplayer might be awarded double the value otherwise associated with thatproperty. For instance, Meditteranean Avenue in one embodiment isassociated with a “3×” multiplier, and the CPU 170 might cause thepayoff to be doubled, effectively to a “6×” multiplier upon the gametoken landing on Mediterranean Avenue and completing the purple colorgroup.

[0101] In one embodiment, once a station is completed, it retains itscompleted status (and its indicator light remains lit) when the bonusround ends and throughout additional bonus rounds until such time as allof the stations in that group are completed, thus defining a completedgroup. The bonus game might be played several times, by several players,before completing any station groups. Upon the completion of a group,the CPU 170 rewards the player as appropriate and then removes thecompleted status of the stations in the station group, causing theindicator lights to be extinguished.

[0102] For example, in the MONOPOLY REEL ESTATE™ game, a first playermight enter the bonus game five times landing, respectively, on IllinoisAve. (red), Ventnor Ave. (yellow), Community Chest (no color), St. JamesPlace (orange) and Pacific Ave. (green), causing the CPU 170 to assigncompleted status and illuminate indicator lights associated with thoseproperties. A second player might then enter the bonus game three times,landing respectively on North Carolina Ave. (green) and Tennessee Ave.(orange), again causing the CPU 170 to assign completed status andilluminate indicator lights associated with those properties. A thirdplayer might then enter the bonus game and land on New York Ave.(orange), thus completing the orange color group. After identifying thatNew York Ave. is completed and that it completes the orange color group,the CPU 170 might then award the player a free bonus spin and clear orremove the completed status and extinguish the indicator lights on theorange properties. If the player were to land on Pennsylvania Ave.(green) in the free spin, thus completing the green color group, the CPU170 would award the player another free bonus spin, clear the completedstatus and extinguish the indicator lights on the green properties.Otherwise, any other outcome would cause the CPU 170 to end the bonusgame and return to the basic game.

[0103] In one embodiment, the free spin feature has a relatively lowtotal payback of 1.9%, so that players will not feel compelled to keepplaying the game until completing a color group (or conversely, toimmediately leave the game after completing a color group), and so thatother players will not be enticed to “sit out” and wait for machineswhich have a large proportion of lit properties.

[0104] Now turning to FIG. 14, there is depicted another gaming machine210 with a board game theme. In one embodiment, the gaming machine 210is operable to play a game entitled MONOPOLY ADVANCE TO BOARDWALK™,based on the MONOPOLY™ board game. MONOPOLY™ is a registered trademarkowned by and used with permission by Hasbro, Inc. and HasbroInternational, Inc., Pawtucket, R.I. Alternatively, the gaming machine210 may be implemented with any of several other board game themes otherthan MONOPOLY™.

[0105] The gaming machine 210 includes a display window 270 throughwhich a player may observe three mechanical reels, 214, 216 and 218. Thegaming machine 210 includes a top box 232 which includes a graphicsdisplay 212 and an adaptation of a game board 262 (e.g., MONOPOLY). Thegraphics display 12 may comprise a dot matrix, CRT, LED, LCD,electro-luminescent display or generally any type of video display knownin the art. The game board 262 comprises a partially translucentmaterial such as glass, plastic, Plexiglas or the like which is backlitby a number of lights 266 (not visible in FIG. 14) in the top box 232.As best observed in FIG. 16a, the facing surface 260 of the top box isimprinted with various artwork, symbols and text associated with theMONOPOLY ADVANCE TO BOARDWALK™ game, including a pay table 250 andinstruction table 252.

[0106]FIG. 15 is a block diagram of a control system suitable foroperating the slot machine 210 of FIG. 14. Coin/credit detector 282signals a CPU 270 when a player has inserted a number of coins or playeda number of credits. Then, after the player has activated a switch 284(e.g., by pulling a lever or pushing a button), the CPU 270 initiatesgame play by setting reels 214, 216, 218 in motion, randomly selecting agame outcome and, using technology well known in the art, causes a reelmotor and step controller 290 to stop the reels 214, 216, 218 at a stopposition corresponding to the pre-selected game outcome. A rotationalposition detector 292 provides feedback to the CPU 270 to ensure thatthe reels 214, 216, 218 are stopped at the correct stop position. Thesymbols displayed on the reels at the preselected stop position defineindicia of the pre-selected game outcome. In one embodiment, the symbolsdisplayed on the reels define the basic game outcome.

[0107] A system memory 286 stores control software, operationalinstructions and data associated with the gaming machine 210. In oneembodiment, the memory 286 comprises a separate read-only memory (ROM)and battery-backed random-access memory (RAM). However, it will beappreciated that the memory 286 may be implemented on any of severalalternative types of memory structures or may be implemented on a singlememory structure. A payoff mechanism 288 is operable in response toinstructions from the CPU 270 to award a payoff of coins or credits tothe player in response to certain winning combinations stored in memory286. As will be described in detail hereinafter, the payoff amountscorresponding to certain combinations is predetermined according to apay table stored in system memory 286. A separate I/O controller 271coupled to the CPU 270 operates the graphics display 212 and top boxlights 266.

[0108] The gaming machine 210 is operable to play a basic game and abonus game. In the embodiment of FIG. 14, the basic game is implementedon the three mechanical reels, 214, 216, 218 with a center payline 276.In one embodiment, the player can observe three symbol positions (e.g.,an upper, center and lower display position) on each reel 214, 216, 218thus defining a symbol group of nine symbols visible through the displaywindow 270. Payline 276 extends through the center display position oneach reel.

[0109] In one embodiment, the symbol group displayed on reels 214, 216,218 may indicate any of four possible basic game outcomes, including (1)a standard winning outcome causing the CPU 270 to award the player apredetermined amount of coin(s) or credit(s) corresponding to adisplayed pay table; (2) a surprise winning outcome causing the CPU 270to award the player a predetermined amount of coin(s) or credit(s)corresponding to a “surprise” winning outcome not identified on adisplayed pay table; (3) a start-bonus outcome causing the CPU 270 toenter a bonus game; and (4) a losing outcome causing the processor 40 tocontinue operation in the basic mode without awarding any coin(s) orcredit(s).

[0110] Generally, both the standard and surprise winning outcomes arecharacterized by the display of one or more predefined combinations ofsymbols. The symbols and payoffs defining the standard and surprisewinning combinations are stored in the game memory 286. In oneembodiment, the symbols and payoffs defining the standard winningcombinations are shown in the pay table 250 (FIG. 16a) on the face ofthe slot machine 210 so that they may be observed by the player, whereasthe symbols defining the surprise winning combinations are not shown onthe top box 232 and hence will likely “surprise” the player when theyresult in a payoff. In the MONOPOLY ADVANCE TO BOARDWALK™ game, thesymbols defining the surprise winning combinations are identified onlygenerally on the top box 232 as a “mystery blank combination” whichstarts the ADVANCE TO BOARDWALK™ bonus game. The specific combination ofBLANK symbols which define the “mystery blank combination” is predefinedand stored in game memory 286.

[0111] The symbols defining the start-bonus combinations are preferablyidentified on the pay table or other portion(s) of the top box display232. For example, as will be described in greater detail hereinafter,the MONOPOLY ADVANCE TO BOARDWALK™ game has two bonus features: a CHANCEbonus feature and an ADVANCE TO BOARDWALK bonus feature. In theembodiment of FIG. 16a, the CHANCE bonus feature and the symbols (i.e.,start-bonus combinations) which trigger the CHANCE bonus feature areexplained in the text underlying the CHANCE icon at the center-left ofthe top box display 232. Specifically, the display 232 includes thefollowing description of the CHANCE bonus feature in the illustratedembodiment:

[0112] CHANCE SYMBOL matches only 7's and BARS on the payline. WhenCHANCE symbol is in a winning combination, the CHANCE BONUS FEATUREstarts in the display. The CHANCE BONUS is a randomly awarded multiplierfrom 2-10 or 2-25 bonus coins. CHANCE SYMBOL does not substitute forWILD.

[0113] The ADVANCE TO BOARDWALK bonus feature and the symbols (i.e.,start-bonus combinations) which trigger the ADVANCE TO BOARDWALK bonusfeature are explained in the field 252 at the lower-right of the top boxdisplay 232, as follows:

[0114] THREE RICH UNCLE MONEYBAGS in any position starts the ADVANCE TOBOARDWALK GAME. Player starts on ‘GO’. A random number shown on thedisplay will move the player around the board. Player collects thedisplayed coins on each space landed upon. Player continues accumulatingcoins until the player lands on a ‘GAME OVER SPACE’, or has been awardedthe ‘6th PASS GO’ BONUS. Drawing a ‘GO TO JAIL’ CARD from CHANCE orCOMMUNITY CHEST will send the player to the ‘IN JAIL’ space, ENDING theBONUS BOARD GAME. GOING TO JAIL does not award ‘PASS GO’ Bonuses. CHANCEand COMMUNITY CHEST board squares award 5-50 credits. Mystery blankscombination start the Advance to Boardwalk Game. PASS GO SIX TIMES ANDWIN OVER 2,100 COINS.

[0115]FIG. 17 shows a set of reel strips for use with the slot machine210 to implement the MONOPOLY ADVANCE TO BOARDWALK™ game. The reelstrips correspond to the reels 214, 216, 218 in FIG. 14 and will beidentified by corresponding reference numerals 214, 216, 218. Each ofthe reel strips 214, 216, 218 include twenty-four symbols (includingblanks) corresponding to twenty-four available reel stopping positions.The symbols include WELD, SEVEN, CHANCE, 3-BAR, 2-BAR, 1-BAR, BLANK andCHERRY which, if displayed in certain predefined combinations relativeto payline 22, define the standard and surprise winning combinations.Three of the BLANK symbols on each reel define mystery blanks which, ifaligned on the payline, will trigger a “surprise” winning outcome Alsoshown on the reel strips 214,216,218 are small RICH UNCLE PENNYBAGS(hereinafter “PENNY”) symbols which are displayed on top of (and therebyshare the same reel stopping position as) some of the other symbols. Inone embodiment, the PENNY symbols do not form the basis of standardwinning combinations in the basic game define start-bonuscombination(s), if displayed in scatter-pay format on the reels 214,216, 218.

[0116] Specifically, the symbols which appear on reel strip 214 include,in sequence 3-BAR, Blank, 1-BAR, Blank, SEVEN, Blank, 1-BAR, Blank,3-BAR/PENNY, Blank, 1-BAR, Blank, 2-BAR, Blank, 1-BAR, Blank, 3-BAR,Blank, 2-BAR/PENNY, Blank, 1-BAR, Blank, 2-BAR and Blank. The symbolswhich appear on reel strip 216 include, in sequence, 3-BAR, Blank,Blank/PENNY, Blank, 2-BAR, Blank, SEVEN, Blank, 1-BAR, Blank, 2-BAR,Blank, WILD/PENNY, Blank, 2-BAR, Blank, CHERRY, Blank, 1-BAR, Blank,CHANCE, Blank, 1-BAR and Blank. Finally, the symbols which appear onreel strip 218 include, in sequence, 3-BAR, Blank, 2-BAR, Blank, 1-BAR,Blank, SEVEN/PENNY, Blank, 1-BAR, Blank, 2-BAR, Blank, 1-BAR, Blank,2-BAR, Blank, 1-BAR, Blank, 2-BAR, Blank, 1-BAR, Blank, 2-BAR and Blank.TABLE C-1 Pay Table for ADVANCE TO BOARDWALK Basic Game 1st COIN 2ndCOIN 3rd COIN 4th COIN SEVEN WILD SEVEN 200 400 1000 3 RICH UNCLEPENNYBAGS in SEVEN SEVEN SEVEN 70 140 210 any position 3BAR 3BAR 3BAR 4080 120 starts the ADVANCE TO 2BAR 2BAR 2BAR 20 40 60 BOARDWALK bonusgame. 1BAR 1BAR 1BAR 10 20 30 (further disclaimers below) anyBAR anyBARanyBAR 5 10 15 — CHERRY — 2 4 6 — WILD — 1 2 3

[0117] Table C-1 is a pay table identifying various winning combinationsof symbols in the MONOPOLY ADVANCE TO BOARDWALK™ game. The winningcombinations include various standard symbol combinations (e.g., SEVEN,WILD, SEVEN) and start-bonus combinations (e.g., “Three Rich UnclePennybags Starts the Advance to Boardwalk Bonus Game). In oneembodiment, the game accepts from one to four coins. The winningstandard combinations can occur for any number of one to four coinsplayed if the indicated symbols are displayed on reels 214, 216, 218 inalignment with the center payline 276. For example, three “1-BAR”symbols displayed on reels 214, 216, 218 on the center payline 276 is astandard winning combination which will pay 10 credits for 1 coinplayed, 20 credits for 2 coins played and 30 credits for 3 or 4 coinsplayed. The “Any Bar” combination is satisfied by any combination ofthree or more “1-BAR,” “2-BAR” and “3-BAR” symbols stopping on thecenter payline 276.

[0118] In one embodiment, the “WILD” symbol acts as a wildcard for allof the BAR combinations. Thus, for example, the combination of “2-BAR,”“WILD” and “2-BAR” is a standard winning combination which would pay thesame as the combination of three “2-BAR” symbols, corresponding to thenumber of coins played. In one embodiment, the “CHANCE” symbol acts as awildcard for “SEVEN” and “BAR” combinations and also triggers the CHANCEbonus feature (to be described later) if it is in a winning combination.Thus, for example, the combination of “2-BAR,” “CHANCE” and “2-BAR” is astandard winning combination which would pay the same as the combinationof three “2-BAR” symbols, corresponding to the number of coins playedand also is a start-bonus combination which starts the CHANCE bonusfeature.

[0119] In one embodiment, if the player wagers 4 coins, and if threeRich Uncle Pennybags (“PENNY”) symbols are displayed in scatter-payformat on reels 214, 216, 218, the game starts the ADVANCE TO BOARDWALKbonus feature (to be described later). In the scatter-pay format, thePENNY symbols are not required to be aligned with the center payline276. Rather, the ADVANCE TO BOARDWALK bonus starts if reel 214 displaysPENNY in either of the upper, center or lower display positions, reel216 displays PENNY in either of the upper, center or lower displaypositions (which need not correspond to the display position of PENNY onreel 214) and reel 218 displays PENNY in either of the upper, center orlower display positions (which need not correspond to the displaypositions of PENNY on reels 214 or 216).

[0120] Table C-2 summarizes payoffs, probabilities and expected valuesassociated with various combinations of the ADVANCE TO BOARDWALK™ game.The combinations are designated, in order of appearance: “non-win,” “1Wild,” “1 Cherry,” “anybar,” “1 Bars,” “anybar/Ch,” “2 Bars,” “1Bar/Ch,” “3 Bars,” “2 Bar/Ch,” “Sevens,” “3 Bar/Ch,” “Seven/Ch,”“7-Wild-7,” “Uncles” and “Surprise.”

[0121] The “Pay/1 Coin,” “Pay/2 Coin,” “Pay/3 Coin” and “Pay/4 coin”columns identify payoff amounts associated with the respectivecombinations in Table C-2. In the case of the standard winningcombinations, the payoff amounts are predetermined amounts stored insystem memory. For example, the “1 Cherry” combination is a standardwinning combination which will award 2 coins or credits in a 1-coingame, 4 coins or credits in a 2-coin game and 6 coins or credits in a 3-or 4-coin game.

[0122] In the case of the “start-bonus” combinations, the payoff amountsrepresent average payoff amounts which may be expected in the bonusgame. For example, the “anybar/Ch” combination (i.e., a winning “anybar”combination with a CHANCE wildcard symbol) will start the CHANCE bonusand will pay, on average, 16.75 coins or credits in a 1-coin game, 33.5coins or credits in a 2-coin game and 50.26 coins or credits in a 3- or4-coin game. The “Uncles” and “Surprise” combinations representcombinations of RICH UNCLE PENNYBAGS (“PENNY”) symbols and mystery blanksymbols which trigger the ADVANCE TO BOARDWALK bonus. Both of thesecombinations are available only with 4 coins played and will pay, onaverage 98.4 coins or credits.

[0123] The “1-3 prob” column identifies the probabilities of hitting thevarious outcomes of Table C-2 associated with a 1-coin, 2-coin and3-coin game in a single spin. The “4cn prob” column identifies theprobabilities of hitting the various outcomes of Table C-2 associatedwith a 4-coin game in a single spin. Where the reels each havetwenty-four reel stop positions, as in the ADVANCE TO BOARDWALK™ game,there are 13,824 (24×24×24) possible symbol combinations. Theprobability of hitting any particular combination in a single spin isdetermined by dividing the number of possible “hits” associated withthat combination (which is a function of the number of reel positions ofthe symbols supporting that combination) by the total number of possiblecombinations (i.e., 13,824). For example, consider the “7-Wild-7”combination. Because there is only one SEVEN symbol on reel 214, oneWILD symbol on reel 216 and one SEVEN symbol on reel 218, there is onlyone “hit” associated with that combination. The probability of hittingthat combination is therefore 7.2×10⁻⁵ (i.e. 1÷13,824). In a 4-coingame, the probability of hitting an “Uncles” combination is 0.00781 andthe probability of hitting a “Surprise” combination is 0.00195.

[0124] The “1 cn EV,” “2 cn EV,” “3 cn EV” and “4 cn EV” columnsidentify the normalized expected values of the outcomes of Table C-2 fora 1-coin game, 2-coin game, 3-coin game and 4-coin game, respectively.These values are computed for each outcome by taking the product of thepay value (or average pay value) associated with that outcome and theprobability associated with that outcome, then dividing by the number ofcoin(s) played. Thus, for example, the “Sevens” outcome has a 1-coinexpected value of 0.005064 (70×7.2×10⁻⁵÷1), a 2-coin expected value of0.005064 (140×7.2×10⁻⁵÷2), a 3-coin expected value of 0.005064(210×7.2×10⁻⁵÷3) and a 4-coin expected value of 0.003798(210×7.2×10⁻⁵÷4). The “Uncles” outcome has a 4-coin expected value of0.192211 (98.41212×0.00781 ÷4) and the “Surprise” outcome has a 4-coinexpected value of 0.048053 (98.41212×0.00195 ÷4).

[0125] The payout rate of the basic game is computed independently for a1-coin, 2-coin, 3-coin and 4-coin game by summing the normalizedexpected values in the respective “1 cn EV,” “2 cn EV,” “3 cn EV” and “4cn EV” columns. In the embodiment shown in Table C-2, the payout ratesfor a 1-coin and 2-coin game are 0.898869 (89.89%), the payout rate fora 3-coin game is 0.908514 (90.85%) and the payout rate for a 4-coin gameis 0.920673 (92.07%).

[0126] The “4th coin Pulls/Hit” column indicates how many pulls, onaverage, would be expected to hit the respective combinations in a4-coin game. This is computed by taking the inverse of the probabilityvalues associated with a 4-coin game.

[0127] The “Max Contribution” column indicates, for a 4-coin game, thepercentage contribution of the respective “4 cn EV” values to the totalpayout rate for a 4-coin game. Thus, for example, for the “Uncles”outcome, the contribution is 20.88% (0.192211÷0.920673). The remaining“Max Contribution” values are computed in similar fashion.

[0128] The CHANCE Bonus Feature

[0129] In the MONOPOLY ADVANCE TO BOARDWALK™ game, if the “CHANCE”symbol is displayed on the payline and is included in a basic winningcombination, the CHANCE bonus game begins. In one embodiment, there isonly one “CHANCE” symbol on reel 216 (the center reel) and, according tothe game rules, it matches only SEVENs and BARs on the payline, thus thecombinations which would trigger the CHANCE bonus are: SEVEN, CHANCE,SEVEN; 3 BAR, CHANCE, 3 BAR; 2 BAR, CHANCE, 2 BAR; 1 BAR, CHANCE, 1 BAR;and ANYBAR, CHANCE, ANYBAR.

[0130] The Chance bonus game can be activated by playing from one-fourcoins. In one embodiment, the CPU 270 sets up the CHANCE bonus game byfirst selecting, from a weighted table, one of several possible sets ofselection elements. Generally, the sets of selection elements comprise acombination of multiplier values and/or fixed coin amounts. Themagnitude of the respective multiplier values and/or fixed coin amountsare unique to each particular set of selection elements. The selectionelements themselves may be varied according to the game program. In oneembodiment, each set includes 10 selection elements but otherwise thenumbers and/or values of multipliers and fixed coin awards may be variedfrom set to set. For example, one of the sets of selection elementsmight include 2×, 3×, 4×, 5×and 10× multipliers, and 2, 5, 10, 20, and25 coin awards, whereas another set might include 2×, 3×, 4×, 5×and 10×multipliers and 5, 10, 25, 50 and 100 coin awards. Still another setmight include 2×, 3×, 5× and 10× multipliers and 2, 5, 10, 25, 50 and100 coin awards.

[0131] In one embodiment, as shown in FIG. 18, the CPU 270 causes theselected set of selection elements to be displayed on the graphicsdisplay 212 in roughly an oval shape around a center area where messagesare displayed. In the illustrated embodiment, the message area promptsthe player to “PRESS ‘SPIN REELS’ TO WIN THE CHANCE BONUS.” From thedisplay screen shown in FIG. 18, the CHANCE bonus is initiated by theplayer pressing the “Spin Reels” button or pulling a lever (not shown).The CPU 270 then operates according to its game program (stored insystem memory 286) to randomly select one of the selection elements fromthe set. In one embodiment, the various selection elements havegenerally different probabilities of being selected, as determined by atable stored in system memory 286. In one embodiment having a set ofselection elements including 2×, 3×, 4×, 5×and 10× multipliers and 2, 5,10, 20 and 25 coin awards, the probabilities of selecting the respectiveselection elements are: 0.219231 for the 2× multiplier; 0.153846 for the3× multiplier; 0.061538 for the 4× multiplier; 0.053846 for the 5×multiplier; 0.069231 for the 10× multiplier; 0.126923 for the 2 coinaward; 0.138462 for the 5 coin award; 0.076923 for the 10 coin award;0.042308 for the 20 coin award; and 0.057692 for the 25 coin award.

[0132] In one embodiment, the selection of the CHANCE bonus awardelement is depicted on the graphic display 212 by highlighting, one at atime, consecutive selection elements in a clockwise sequence, quickly atfirst and then slowing down and stopping to reveal the selected awardelement, which might be a fixed coin amount or a multiplier. At thispoint, the message area will display the total amount of coins orcredits won. For example, if the award from the basic game reels was 10credits, and the highlight stopped on a 25 Coin amount, the message areawill contain “10+25=35 COINS”. If, however, the award from the basicgame reels was 10 credits, and the highlight stopped on a 4× multiplier,the message area will contain “10×4=40 COINS”. The game would then totalthe amount won on the win meter and show a total screen on the display112 announcing how many coins were won in the CHANCE bonus game. If theamount won is over the selected handpay level, a jackpot display andanimation will then be shown on the display 112. In one embodiment,after the amount won is credited or payed out, the CHANCE bonus featureends and the game returns to the basic game.

[0133] In one embodiment of a 4-coin game, the coin awards aremultiplied by two for two coins bet and multiplied by three for three orfour coins were bet. The fourth coin allows the player the opportunityto play the MONOPOLY ADVANCE TO BOARDWALK™ bonus game and does notincrease the value of the CHANCE bonus.

[0134] The ADVANCE TO BOARDWALK™ Bonus Game

[0135] In one embodiment, the CPU 270 enters the ADVANCE TO BOARDWALK™bonus game when the player is betting four coins and a special“start-bonus” combination of three RICH UNCLE PENNYBAGS (“PENNY”)symbols occurs on the reels 214, 216, 218, in scatter-pay format, in thebasic game. As described earlier, scatter-pay format means that thescatter pay symbols (e.g., “PENNY” symbols in the ADVANCE TO BOARDWALK™game) may be displayed in either the upper, lower or center position onthe respective reels.

[0136] The ADVANCE TO BOARDWALK™ bonus game has a board-game (e.g.,MONOPOLY) theme and is implemented on the top box game board 262 andgraphics display 212. Upon initially entering the bonus game, the CPU 70causes an introductory animation to be displayed on the graphics display212 with an audio fanfare and then signals I/O controller 271 toilluminate the GO square on the top box MONOPOLY board 262. The playeris prompted to spin the reels to to play the bonus game. Then, in oneembodiment, the CPU 270 operates to select an integer-value movementindicator and causes the selected movement indicator to be displayed onthe graphics display 212.

[0137] In one embodiment, the movement indicator is not immediatelyshown on the graphics display 212 but is revealed slowly so as toheighten the player's anticipation of the indicator. In one embodiment,the graphics display 212 shows the movement indicator on a display fieldwhich is intentionally fuzzy or cloudy at first, so as to “hide” theindicator but which is slowly cleared up to reveal the selectedindicator. In one embodiment of the MONOPOLY ADVANCE TO BOARDWALK™ game,for example, the graphics display shows an animation of a Rich UnclePennybags character seated at a desk-type “control panel.” A messagearea on the control panel includes an animated computer ortelevision-type monitor adapted to reveal the selected indicator. Themonitor is filled with “static” at first so as to obscure the movementindicator. For example, the message area on the control panel mightread, “YOU MOVE [blank] SPACES,” where the blank is filled in by thenumber to be displayed on the monitor. After a short time, the RichUncle Pennybags character twiddles dials and levers on the control boardto clear up the static and reveal the selected indicator. At this point,for example, the message area might read “YOU MOVE [7] SPACES,” wherethe “7” is displayed on the animated monitor.

[0138] In one embodiment, the movement indicator (e.g., “7”) identifiesan amount of spaces, from two to twelve, which the token will be movedfrom its previous position on the game board, in much the same manner aswould a roll of dice. In one embodiment, the CPU 270 selects themovement indicator pseudo-randomly, that is, certain indicator valuesmight occur more frequently than other indicator values, depending onthe space the player is presently “on.” For example, the CPU 270 mightbe more likely to select a movement indicator of “7” if the player wereon INDIANA AVENUE (thus landing the player on GO TO JAIL), than if theplayer were on ILLINOIS AVENUE. In one embodiment, a plurality ofmovement tables is stored in game memory, wherein each movement tablecorresponds to a particular square of the MONOPOLY board. The CPU 270selects, from the movement table corresponding to present space, amovement indicator by first picking a random number, then consulting themovement table to determine the movement indicator corresponding to therandom number.

[0139] In one embodiment, the movement tables define, for each square, anumber of occurrences of each possible outcome from two to twelve. Forexample, one movement table might define a set of 46 possibleoccurrences, including 2 occurrences associated with a movement of 2spaces, 2 occurrences associated with a movement of 3 spaces, 3occurrences associated with a movement of 4 spaces, 5 occurrencesassociated with a movement of 5 spaces, 8 occurrences associated with amovement of 6 spaces, 6 occurrences associated with a movement of 7spaces, 5 occurrences associated with a movement of 8 spaces, 7occurrences associated with a movement of 9 spaces, 6 occurrencesassociated with a movement of 10 spaces, 1 occurrence associated with amovement of 11 spaces and 1 occurrence associated with a movement of 12spaces.

[0140] The CPU 270 might select a movement indicator from the exampletable by selecting a random number from one to 46, then stepping througheach occurrence until it finds the movement indicator corresponding tothat random number. For example, for the example movement table above, arandom number of 5 might indicate that the selected movement indicatorwould be “4,” since the first two “step throughs” are 2, the next two“step throughs” are 3 and the fifth step ends on an indicator of 4.

[0141] After the selection of a movement indicator number and display ofthe indicator on the graphics display 212, the CPU 270 operates toilluminate, one space at a time, the appropriate squares on the gameboard 262 (e.g., MONOPOLY board) from the previous position to theposition determined by the movement indicator.

[0142] In one embodiment, when the lights stops moving for each roll, ananimated character icon (e.g., Rich Uncle Pennybags) on the graphicsdisplay 212, announces the name of the square landed on and the amountof coins or credits, if any, associated with the square. In oneembodiment, the bonus game continues with consecutive selections ofmovement indicators, and corresponding movement around the game board,until the player “lands” on a designated square which ends the bonusgame. In one embodiment, the CPU 270 will end the bonus game if theplayer lands on the IN JAIL, INCOME TAX or LUXURY TAX squares, otherwisewill continue the bonus game.

[0143] If the player lands on an ELECTRIC COMPANY, WATER WORKS or FREEPARKING square during the bonus round, the CPU 270 selects a win amountfrom a plurality of possible win amounts associated with the square. Inone embodiment, the CPU 270 triggers an appropriate animation on thegraphics display 212 to illustrate the selection of a win amount. FIGS.19, 20 and 21, show exemplary displays which might occur in response tothe player landing on WATER WORKS, ELECTRIC COMPANY or FREE PARKING,respectively.

[0144] Generally, each of the WATER WORKS, ELECTRIC COMPANY and FREEPARKING displays show a pre-selected award value and a number of other,different values at various graphical locations. The display animationappears to “select” an award value, which has already been pre-selectedby the CPU 270, by pointing to the pre-selected value or “erasing” theother values. In FIG. 19 (WATER WORKS), for example, there are fourpossible award values (e.g., 5, 10, 25 and 50) displayed at fourgraphical locations (e.g., underneath four pipes). An animated RichUncle Pennybags character turns a valve, causing water to come out ofone of the pipes and “wash away” the underlying displayed value. He willdo this three times, causing three of the award values to be “washedaway,” and the player will be awarded the remaining award value. In FIG.20 (ELECTRIC COMPANY), there are four possible award values (e.g., 5,20, 25 and 50) displayed on four light bulbs. An animated Rich UnclePennybags character presses a button, causing one of the light bulbs tolight up then explode, so as to erase the award value associated withthe exploded bulb. As in FIG. 19, he will do this three times, causingthree of the award values to be erased, and the player will be awardedthe remaining award value. In FIG. 21 (FREE PARKING), there are sevenpossible award values (e.g., 10, 15, 20, 25, 50, 100 and 200) displayedon an animated parking meter. A pointer in the parking meter moves backand forth, then slowly comes to a stop so as to point to one of theaward values, and the player is awarded the indicated award value.

[0145] In one embodiment, the indicated award values for the ELECTRICCOMPANY, WATER WORKS and FREE PARKING squares are pre-selected by theCPU 270 from weighted tables of award values stored in game memory. TheCPU 270 selects, from the award table corresponding to the ELECTRICCOMPANY, WATER WORKS or FREE PARKING space, an award by first picking arandom number, then consulting the appropriate award table to determinethe award corresponding to the random number.

[0146] Suppose, for example, an ELECTRIC COMPANY square has fivepossible awards: 5, 10, 20, 25 or 50 coins. An award table associatedwith the ELECTRIC COMPANY square might define a set of eight possibleoccurrences of the various awards: 2 occurrences associated with anaward of 5 coins, 2 occurrences associated with an award of 10 coins, 2occurrences associated with an award of 20 coins, 1 occurrenceassociated with an award of 25 coins and 1 occurrence associated with anaward of 50 coins. The CPU 270 might select an award from the awardtable by selecting a random number from one to 8, then stepping througheach occurrence until it finds the award corresponding to that randomnumber. Continuing the above example, a random number of 5 mightindicate that the selected award would be 20 coins, since the first two“step throughs” are 5 coins, the next two “step throughs” are 10 coinsand the next step ends on an award of 20 coins.

[0147] Similarly, suppose the FREE PARKING square has seven possibleawards: 10, 15, 20, 25, 50, 100 and 200 coins. An award table associatedwith the FREE PARKING square might define a set of nine possibleoccurrences of the various awards: 1 occurrence associated with an awardof 10 coins, 1 occurrence associated with an award of 15 coins, 2occurrences associated with an award of 20 coins, 2 occurrencesassociated with an award of 25 coins, 1 occurrence associated with anaward of 50 coins, 1 occurrence associated with an award of 100 coinsand 1 occurrence associated with an award of 200 coins. The CPU 270might select an award from the award table by selecting a random numberfrom one to 9, then stepping through each occurrence until it finds theaward corresponding to that random number. Continuing the above example,a random number of 5 might indicate that the selected award would be 25coins, since the first “step through” is 10 coins, the next “stepthrough” is 15 coins, the next two “step throughs” are 20 coins and thenext step ends on an award of 25 coins.

[0148] If the player lands on CHANCE or COMMUNITY CHEST, the CPU 270triggers an animation on graphics display 212 which shows the top cardof a pile of cars flipping up to reveal the “Chance” or “CommunityChest” outcomes. The art on the cards resembles the cards in an actualMONOPOLY™ game. Generally, the “Chance” and “Community Chest” outcomescomprise awards of fixed coin values (e.g., “BANK PAYS YOU DIVIDEND OF25 COINS), or move the player to a new space (e.g., ADVANCE TO NEARESTRAILROAD). If the player is moved to a property, the movement isindicated on the top box board 262 and an animation associated with theproperty is shown on the graphics display 212.

[0149] If the player draws a GO TO NEAREST UTILITY card, the light willmove to either ELECTRIC COMPANY or WATER WORKS clockwise (whichever isnearest). In one embodiment, if movement to the nearest utility causesthe player to pass GO, the player will be awarded a “passing GO bonus,”in addition to the award, if any, associated with the nearest utility.

[0150] If the player draws a GO TO JAIL card, the game will play ananimation of RICH UNCLE PENNYBAGS going to jail, and the light willquickly move counter-clockwise to the IN JAIL space. If the player stopson LUXURY TAX, INCOME TAX or IN JAIL, the display 212 will show anappropriate animation including a display of the total coins won in thebonus game. The CPU 270 will cause the payoff mechanism 288 to awardcoins or credits as appropriate, corresponding to the amount won in thebonus game and then return to the basic spinning reel game.

[0151] In one embodiment, a bonus is awarded whenever the player passes,or lands on, the GO square. As best observed in FIG. 16b, the bonusesare enumerated by a number of indicator lights 290 on the top boxMONOPOLY board 262. In the illustrated embodiment, there are sevenindicator lights associated with escalating 5, 10, 25, 100, 150, 500 and1,500 coin bonuses. When the game begins, the player receives anautomatic 5 coin bonus for being on GO and, accordingly, the 5 COINindicator is lit on the board 262. If the player passes GO on his firstcycle 1 around the board, the 10 COIN indicator will light, and theplayer will be awarded with 10 coins. If the player cycles around theboard again, then the 25 COIN indicator will light, and the player willbe awarded with 25 coins. If the player continues to pass GO a third,fourth, fifth and sixth time, the respective 100 COIN, 150 COIN, 500COIN and 1500 COIN bonus indicators will become lit and the player willbe awarded with 100 coins, 150 coins, 500 coins and 1500 coinsrespectively.

[0152] In one embodiment, the board may be cycled a maximum of sixtimes. If a player successfully cycles the board six times, the bonusgame will end and player will receive all accumulated awards, plus the1500 coin bonus, plus the award, if any, associated with the finalspace. If the final space causes the player to move to another square(e.g., GO TO NEAREST UTILITY), the player will be awarded the bonus, ifany associated with that other square. For example, suppose the playerhas completed five trips around the board and has accumulated 1754 coinsor credits so far in the bonus game. Suppose further that the player iscurrently on PARK PLACE and Rich Uncle Pennybags selects a movementindicator of “5,” causing the player to pass GO and land on theCOMMUNITY CHEST square. The player will be awarded the 1500 coin bonusfor passing GO the sixth time plus an amount associated with theCOMMUNITY CHEST square. Continuing the example, suppose Rich UnclePennybags selects a COMMUNITY CHEST card of GO TO NEAREST UTILITY. Theplayer will move to the next utility, ELECTRIC COMPANY, and will beawarded a selected value, say 25 coins. The bonus game will end afterdisplaying, and then paying (in the present example), a win amount of3279 coins (e.g., 1754+1500+25).

[0153] Now turning to FIG. 22, there is depicted another gaming machine310 with a board game theme. In one embodiment, the gaming machine 310is operable to play a game entitled MONOPOLY ROLL & WIN™, based on theMONOPOLY™ board game. MONOPOLY™ is a registered trademark owned by andused with permission by Hasbro, Inc. and Hasbro International, Inc.,Pawtucket, R.I. Alternatively, the gaming machine 110 may be implementedwith any of several other board game themes other than MONOPOLY™.

[0154] The gaming machine 310 includes a display window 370 throughwhich a player may observe three mechanical reels, 314, 316 and 318. Thegaming machine 310 includes a top box 332 which includes a graphicsdisplay 312, mechanical dice 364 and an adaptation of a game board 362(e.g., MONOPOLY). The graphics display 312 may comprise a dot matrix,CRT, LED, LCD, electro-luminescent display or generally any type ofvideo display known in the art. The game board 362 comprises a partiallytranslucent material such as glass, plastic, Plexiglas or the like whichis backlit by a number of lights 366 (not visible in FIG. 22) in the topbox 332. As best observed in FIG. 24, the facing surface 360 of the topbox is imprinted with various artwork, symbols and text associated withthe MONOPOLY ROLL & WIN™ game, including a pay table 350.

[0155]FIG. 23 is a block diagram of a control system suitable foroperating the slot machine 310 of FIG. 22. Coin/credit detector 382signals a CPU 370 when a player has inserted a number of coins or playeda number of credits. Then, after the player has activated a switch 384(e.g., by pulling a lever or pushing a button), the CPU 370 initiatesgame play by setting reels 314, 316, 318 in motion, randomly selecting agame outcome and, using technology well known in the art, causes a reelmotor and step controller 390 to stop the reels 314, 316, 318 at a stopposition corresponding to the pre-selected game outcome. A rotationalposition detector 392 provides feedback to the CPU 370 to ensure thatthe reels 314, 316, 318 are stopped at the correct stop position. Thesymbols displayed on the reels at the preselected stop position defineindicia of the pre-selected game outcome. In one embodiment, the symbolsdisplayed on the reels define the basic game outcome.

[0156] A system memory 386 stores control software, operationalinstructions and data associated with the gaming machine 310. In oneembodiment, the memory 386 comprises a separate read-only memory (ROM)and battery-backed random-access memory (RAM). However, it will beappreciated that the memory 386 may be implemented on any of severalalternative types of memory structures or may be implemented on a singlememory structure. A payoff mechanism 388 is operable in response toinstructions from the CPU 370 to award a payoff of coins or credits tothe player in response to certain winning combinations stored in memory386. As will be described in detail hereinafter, the payoff amountscorresponding to certain combinations is predetermined according to apay table stored in system memory 386. A separate I/O controller 371coupled to the CPU 370 operates the graphics display 312, mechanicaldice 364 and top box lights 366.

[0157] The gaming machine 310 is operable to play a basic game and abonus game. In the embodiment of FIG. 22, the basic game is implementedon the three mechanical reels, 314, 316, 318 with a center payline 376.In one embodiment, the player can observe three symbol positions (e.g.,an upper, center and lower display position) on each reel 314, 316, 318thus defining a symbol group of nine symbols visible through the displaywindow 370. Payline 376 extends through the center display position oneach reel.

[0158] In one embodiment, the symbol group displayed on reels 314, 316,318 may indicate any of three possible basic game outcomes, including(1) a standard winning outcome causing the CPU 370 to award the player apredetermined amount of coin(s) or credit(s) corresponding to adisplayed pay table; (2) a multiplier bonus outcome (e.g., a ROLL THEDICE feature) causing the CPU 370 to award the player the product of apredetermined amount of coin(s) or credit(s) and a randomly determinedmultiplier; (3) a start-bonus outcome causing the CPU 370 to enter abonus game (e.g., the ROLL & WIN bonus); and (4) a losing outcomecausing the CPU 370 to continue operation in the basic mode withoutawarding any coin(s) or credit(s).

[0159] Generally, the standard winning outcomes are characterized by thedisplay of one or more predefined combinations of symbols. The symbolsand payoffs defining the standard winning combinations are stored in thegame memory 386. In one embodiment, the symbols and payoffs defining thestandard winning combinations are shown in the pay table 350 (FIG. 24)on the face of the slot machine 310 so that they may readily be observedby the player. Preferably, the symbols defining the ROLL THE DICEfeature and ROLL & WIN bonus are also identified on the pay table orother portion(s) of the top box display 332.

[0160]FIG. 25 shows a set of reel strips for use with the slot machine310 to implement the MONOPOLY ROLL & WIN™ game. The reel stripscorrespond to the reels 314, 316, 318 in FIG. 14 and will be identifiedby corresponding reference numerals 314, 316, 318. Each of the reelstrips 314, 316, 318 include twenty-two symbols (including blanks)corresponding to twenty-two available reel stopping positions. Thesymbols include RICH UNCLE PENNYBAGS (“PENNY”), WILD, WILD DICE, SEVEN,3-BAR, 2-BAR, 1-BAR, BLANK and CHERRY which, if displayed in certainpredefined combinations relative to payline 376, define the standard andsurprise winning combinations.

[0161] Specifically, the symbols which appear on reel strip 314 include,in sequence I-BAR, Blank, PENNY, Blank, 2-BAR, Blank, PENNY, Blank,1-BAR, Blank, PENNY, Blank, SEVEN, Blank, 2-BAR, Blank, 3-BAR, Blank,PENNY, Blank, 2-BAR and Blank. The symbols which appear on reel strip316 include, in sequence 2-BAR, Blank, WILD, Blank, PENNY, Blank, WILDDICE, Blank, PENNY, Blank, WILD, Blank, SEVEN, Blank, PENNY, Blank,3-BAR, Blank, WILD, Blank, 1-BAR and Blank. Finally, the symbols whichappear on reel strip 318 include, in sequence 2-BAR, Blank, CHERRY,Blank, 3-BAR, Blank, 1-BAR, Blank, PENNY, Blank, SEVEN, Blank, PENNY,Blank, CHERRY, Blank, PENNY, Blank, 1-BAR, Blank, CHERRY and Blank.TABLE D-1 Pay Table for ROLL & WIN ™ Basic Game Reel1 Reel2 Reel3 1Coin2Coin 3Coin 4Coin Seven Seven Seven 50 100 150 150 3Bar 3Bar 3Bar 40 80120 120 2Bar 2Bar 2Bar 20 40 60 60 1Bar 1Bar 1Bar 10 20 30 30 AnyBarAnyBar Anybar 5 10 15 15 Anything Wild Cherry 5 10 15 15 AnythingAnything Cherry 2 4 6 6

[0162] Table D-1 is a pay table identifying various standard winningcombinations of symbols in the MONOPOLY ROLL & WIN™ game. In oneembodiment, the game accepts from one to four coins. The winningstandard combinations can occur for any number of one to four coinsplayed if the indicated symbols are displayed on reels 314, 316, 318 inalignment with the center payline 376. For example, three “1-BAR”symbols displayed on reels 314, 316, 318 on the center payline 376 is astandard winning combination which will pay 10 credits for 1 coinplayed, 20 credits for 2 coins played and 30 credits for 3 or 4 coinsplayed. The “AnyBar” combination is satisfied by any combination ofthree or more “1-BAR,” “2-BAR” and “3-BAR” symbols stopping on thecenter payline 376.

[0163] In one embodiment, the “WILD” and “WILD DICE” symbols acts aswildcards for any other symbol on the payline 376. Where the “WILD”symbol is used to complete a winning combination, the payout will be thesame as the standard winning combination as if completed without theWILD symbol. Thus, for example, the combination of “2-BAR,” “WILD” and“2-BAR” is a standard winning combination which would pay the same asthe combination of three “2-BAR” symbols, corresponding to the number ofcoins played. Where the “WILD DICE” symbol is used to complete a winningcombination, the ROLL THE DICE FEATURE is triggered to identify amultiplier value, as heretofore described, and the multiplier value isused to multiply the amount otherwise associated with the combination.

[0164] The ROLL THE DICE Multiplier Feature

[0165] In the MONOPOLY ROLL & WIN™ game, if the “WILD DICE” symbol isdisplayed on the payline 376 and is included in a wining combination,the ROLL THE DICE multiplier feature begins. In one embodiment, there isonly one “WILD DICE” symbol on reel 316 (the center reel) and thecombinations which would trigger the ROLL THE DICE feature are: SEVEN,WILD DICE, SEVEN; 3 BAR, WILD DICE, 3 BAR; 2 BAR, WILD DICE, 2 BAR; 1BAR, WILD DICE, 1 BAR; ANYBAR, WILD DICE, ANYBAR and PENNY, WILD DICE,PENNY. The PENNY, WILD DICE, PENNY combination also triggers the ROLL &WIN bonus game, to be described later.

[0166] The ROLL THE DICE feature can be activated by playing fromone-four coins. When the WILD DICE symbol appears in a standard winningcombination, the CPU 370 activates the ROLL THE DICE feature by randomlyselecting a multiplier value, then multiplies the base amount associatedwith the standard winning combination by the selected multiplier value.When the WILD DICE symbol appears in the PENNY, WILD DICE, PENNYcombination, a “start-bonus” combination which also triggers the ROLL &WIN bonus game, the CPU 370 enters the ROLL & WIN bonus game first andthen, after the bonus game has ended, randomly selects a multipliervalue and multiplies the amount won in the bonus game by the selectedmultiplier value.

[0167] In one embodiment, the CPU 370 selects the multiplier value byselecting a number corresponding to the roll of two six-sided dice. Thisis accomplished in one embodiment by randomly selecting two integervalues from one to six (each corresponding to a roll of a singlesix-sided die), then summing the integer values to arrive at themultiplier value. Specifically, there are 36 possible outcomes of thetwo integer values which might occur: (1,1), (1,2), (1,3), (1,4), (1,5),(1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3),(3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1),(5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5) and(6,6). These outcomes correspond to 11 possible sums: 2 (1 occurrence),3 (2 occurrences), 4 (3 occurrences), 5 (4 occurrences), 6 (5occurrences), 7 (6 occurrences), 8 (5 occurrences), 9 (4 occurrences),10 (3 occurrences), 11 (2 occurrences) and 12 (1 occurrence).

[0168] In one embodiment, each of the possible outcomes of integervalues (corresponding to the roll of two dice) has an equal probabilityof occurrence and consequently, the probability of the CPU 370 selectingthe various multiplier values (corresponding to the sum of two fairdice) is as follows: 2.7% (i.e., 1÷36) for the “2×” and “12×”multipliers; 5.5% (i.e., 2÷36) for the “3×” and “11×” multipliers; 8.3%(i.e., 3÷36) for the “4×” and “10×” multipliers; 11.1% (i.e., 4÷36) forthe “5×” and “9×” multipliers; 13.9% (i.e., 5÷36) for the “6×” and “8×”multipliers; and 16.7% (i.e., 6∓36) for the “7×” multiplier.

[0169] In one embodiment, the selection of the ROLL THE DICE multiplieris depicted both graphically, on the graphic display 312 andmechanically, by the mechanical dice 364. On the graphics display 312,the CPU 370 generates a display of two dice which are rolling at first,then stop, one at a time to reveal two die faces. The die faces selectedfor display correspond to the integer values from one to six selected bythe CPU 370. For example, having selected integer values of “1” and “6,”the CPU 370 will display a pair of dice, one of which indicates a rollof “1” and the other indicating a roll of “6.” The CPU 370 then adds thetwo integer values to determine the multiplier value (e.g., “7×”) whichin one embodiment is displayed adjacent to the two die faces on thegraphics display 312. Similarly, the CPU 370 causes the two mechanicaldice 364 to rotate or “roll” at first, then stop, one at a time toreveal two die faces. The die faces on the mechanical dice 364correspond to the die faces on the graphics display 312.

[0170] Then, the CPU 370 then generates a screen on the graphics display312 showing the total win. For example, suppose a “7×” multiplier isselected by the CPU 370 in a ROLL THE DICE feature which resulted from aSEVEN, WILD DICE, SEVEN symbol combination. In one embodiment, thegraphics display shows the basic win amount associated with the SEVEN,WILD DICE, SEVEN symbol combination (e.g., 150 coins with 3 coinsplayed), the selected multiplier (e.g., “7×”) and the product of themultiplier and basic win amount (e.g., 1050 coins).

[0171] The ROLL & WIN™ Bonus Game

[0172] In one embodiment, the CPU 370 enters the ROLL & WIN™ bonus gamewhen the player is betting four coins and a special “start-bonus”combination of three RICH UNCLE PENNYBAGS (“PENNY”) symbols occurs onthe center payline 376 of reels 314, 316, 318 in the basic game. TheROLL & WIN™ bonus game has a board-game (e.g., MONOPOLY) theme and isimplemented on the top box game board 362 and graphics display 312. Uponinitially entering the bonus game, the CPU 370 causes an introductoryanimation to be displayed on the graphics display 312 with a musicaljingle and then operates to display an animation of a game tokentraveling around a MONOPOLY board. The CPU 370 also signals I/Ocontroller 371 to illuminate the appropriate to illuminate a startingsquare on the top box game board 362 and then illuminate successivesquares around the board in step-wise fashion, rapidly at first andthen, after a couple of revolutions, slowing down and stopping on anindicated square. Generally, the indicated square is randomly determinedby the CPU 370 prior to the illumination of successive squares on thetop box game board 362.

[0173] In one embodiment, when the player “lands” on the indicatedsquare, the graphics display 312 shows an animation for that square. Asbest observed in FIG. 24, the squares of the game board 362 in oneembodiment of the MONOPOLY ROLL & WIN game are: “GO,” “BALTIC &MEDITTERANEAN AVENUE” (hereinafter “BALTIC”), “READING & PENNSYLVANIA &B. & O. & SHORT LINE RAILROAD” (hereinafter “RAILROAD”), “CONNECTICUT &VERMONT & ORIENTAL AVENUE” (hereinafter “VERMONT”), “IN JAIL,” “VIRGINIA& STATES AVENUE & ST. CHARLES PLACE” (hereinafter “VIRGINIA”), “CHANCE,”NEW YORK & TENNESSEE AVENUE & ST. JAMES PLACE” (hereinafter “NEW YORK”),“FREE PARKING,” “KENTUCKY & INDIANA & ILLINOIS AVENUE” (hereinafter“ILLINOIS”), “UTILITIES,” “MARVIN GARDENS & VENTNOR & ATLANTIC AVENUE”(hereinafter “MARVIN GARDENS”), “GO TO JAIL,” “PENNSYLVANIA & NORTHCAROLINA & PACIFIC AVENUE” (hereinafter “PENNSYLVANIA”), “COMMUNITYCHEST” and “BOARD WALK & PARK PLACE” (hereinafter “BOARDWALK”).

[0174] When the player lands on a square, the CPU 370 causes the playerto be awarded the amount, if any, associated with the square. If theplayer is moved to a property, the movement is indicated on the top boxboard 362, an animation of the property is shown on the graphics display312 and the player is awarded an amount, if any associated with thesquare. In one embodiment, the CPU 370 returns to the basic game afterlanding on a property square. If the game token 140 lands on a CHANCE orCOMMUNITY CHEST square, the CPU 370 randomly selects an outcome from aplurality of possible CHANCE and COMMUNITY CHEST outcomes, and causesthe graphics display 312 to display the selected outcome. If the CHANCEor COMMUNITY CHEST outcome is a fixed coin award, the graphics display312 shows an animation of the award, the player is awarded thedesignated amount and then the CPU 370 returns to the basic game. If theplayer is moved to a new space as a result of a CHANCE or COMMUNITYCHEST outcome, the movement is indicated on the top box board 362, ananimation of the square is shown on the graphics display 312, the playeris awarded an amount, if any associated with the square and then the CPU370 returns to the basic game.

[0175] Table D-2 identifies various pay values, probabilities andexpected values associated with the squares of the game board 362 in oneembodiment of the MONOPOLY ROLL & WIN bonus game. The “Pay” column ofTable D-2 identifies payoff amounts associated with the various squares.Other than the CHANCE and COMMUNITY CHEST squares, the payoff amountsare predetermined amounts stored in system memory. For example, the “GO”square will pay 200 coins or credits, the “BALTIC” square will pay 20coins or credits, and so forth. In one embodiment, the IN JAIL and GO TOJAIL squares have zero value, consequently a player landing on thosesquares will not be paid any credits in the bonus game. In the case ofthe CHANCE and COMMUNITY CHEST squares, the payoff amounts representaverage payoff amounts which may be expected by landing on CHANCE orCOMMUNITY CHEST, respectively. In one embodiment, both the CHANCE andCOMMUNITY CHEST squares will pay, on average 62.4 coins or credits inthe bonus game.

[0177] The various CHANCE and COMMUNITY CHEST outcomes, and their payvalues, probabilities and expected values in one embodiment areidentified in Tables D-3 and D-4, above. Generally, the CHANCE andCOMMUNITY CHEST outcomes include awards of fixed coin values (e.g.,“LIFE INSURANCE MATURES,” $100) or instructions for movement to aparticular square (e.g., ADVANCE TO BOARDWALK), where the indicatedsquare is associated with a fixed coin award. As identified in TableD-3, the COMMUNITY CHEST outcomes range in value between 10 coins orcredits (e.g., “BEAUTY CONTEST”, 10 coins) to a maximum of 200 coins orcredits (e.g., ADVANCE TO GO, and BANK ERROR IN YOUR FAVOR). The averagevalue of the COMMUNITY CHEST square is 62.4 coins or credits. Asidentified in Table D-4, the CHANCE outcomes range in value between 10coins or credits (e.g., “DOG SHOW”, 10 coins) to a maximum of 1000 coinsor credits (e.g., ADVANCE TO BOARDWALK).

[0178] In one embodiment, the likelihood of landing on a particularsquare is predefined and stored in an occurrence probability table ingame memory. The CPU 370 selects a particular square in a manner whichis consistent with the occurrence probability table. Generally, theoccurrence probability table might cause certain squares to be landed onmore frequently than other squares. In Table D-2, the “Occ” columnidentifies a predefined number of outcomes or “occurrences” of eachsquare of the MONOPOLY ROLL & WIN game board, and the “Prob” columnidentifies the probability of selecting or “landing” on the respectivesquares. An inspection of Table D-2 reveals that there is only 1outcome, out of 12,802 possible outcomes, which will result in theplayer landing on the IN JAIL square. Similarly, there is only 1outcome, out of 12,802 possible outcomes, which will result in theplayer landing on the GO TO JAIL square. Thus, the probability of theplayer landing on IN JAIL or GO TO JAIL (and thereby getting no award)is very small, 7.811×10⁻⁵ (i.e., 1÷12,802). The probability of landingon the other squares is generally much greater and also corresponds tothe predefined number of outcomes or “occurrences” associated with thesquares. For example, consider the “GO” square. The “Occ” column ofTable D-1 indicates that there are 480 outcomes, out of 12,802 possibleoutcomes, which will result in the player landing on the GO square.Thus, the probability of the player landing on the GO square (andthereby getting an award of 200 coins or credits) is 0.037494 (i.e.,480÷12,802). The probability of landing on other squares is computedfrom the “Occ” column in similar fashion.

[0179] Similarly, in one embodiment, the likelihood of selecting certainCHANCE or COMMUNITY CHEST cards is predefined and stored in anoccurrence probability table in game memory. The CPU 370 selects aparticular CHANCE or COMMUNITY CHEST card in a manner which isconsistent with the occurrence probability table. Generally, theoccurrence probability table might cause certain cards to be “drawn”more frequently than other cards. In Tables D-3 and D-4, respectively,the “Occ” column identifies a predefined number of outcomes or“occurrences” which might occur as a result of landing on CHANCE andCOMMUNITY CHEST on the MONOPOLY ROLL & WIN game board. The “Prob” columnidentifies the probability of selecting or “drawing” the respectiveCHANCE and COMMUNITY CHEST outcomes. The various probabilities of theCHANCE and COMMUNITY CHEST outcomes are computed by dividing the numberof occurrences of the particular outcome by the total number of CHANCEor COMMUNITY CHEST outcomes, as appropriate. For example, consider the“ADVANCE TO GO” outcome in COMMUNITY CHEST. Table D-3 shows that thereare 4 outcomes, out of 100 possible COMMUNITY CHEST outcomes, which willresult in drawing the “ADVANCE TO GO” card. Thus, having landed on theCOMMUNITY CHEST square, the probability of the player drawing the“ADVANCE TO GO” card (and thereby getting an award of 200 coins orcredits) is 0.04 (i.e., 4÷100). Next consider the “ADVANCE TO GO”outcome in CHANCE. Table D-4 shows that there are 12 outcomes, out of300 possible CHANCE outcomes, which will result in drawing the “ADVANCETO GO” card. Thus, having landed on the CHANCE square, the probabilityof the player drawing the “ADVANCE TO GO” card (and thereby getting anaward of 200 coins or credits) is 0.04 (i.e., 12÷300). The probabilityof drawing other cards is computed in similar fashion.

[0180] The “EV” column identifies the expected values associated withthe various squares (Table D-2), COMMUNITY CHEST cards (Table D-3) orCHANCE cards (Table D-4). These values are computed for each outcome bytaking the product of the pay value (or average pay value) associatedwith that outcome and the probability associated with that outcome.Thus, for example, the “GO” square has an expected value of 7.49882831(i.e., 200×0.037494142), and the “ADVANCE TO GO” card (in both CHANCEand COMMUNITY CHEST) has an expected value of 8 (i.e., 200×0.04).

[0181] The “Pulls/Hit” value represents the number of times, on average,that the game must be played before landing on the particular square(Table D-2) or drawing the particular CHANCE or COMMUNITY CHEST cards(Tables D-3 and D-4). The “Pulls/Hit” column is simply the inverse ofthe “Prob” values in Tables D-2, D-2 and D-4. Thus, for example, the“GO” square has a “Pulls/Hit” value of 26.67 (i.e., 1÷0.037494142), andthe “ADVANCE TO GO” card (in both CHANCE and COMMUNITY CHEST) has a“Pulls/Hit” value of 25 (i.e., 1÷0.04).

[0182] Table D-5 identifies various symbol combinations, probabilitiesand expected values associated with the ROLL & WIN game according to oneembodiment of the present invention. The combinations include variousstandard winning combinations including “777,” “3B3B3B,” “2B2B2B,”“1B1B1B,” “ABABAB,” “2 Cherry” and “Cherry;” various combinations whichwill start the ROLL & WIN bonus game including “UncleUncleUncle;” andvarious combinations which will trigger the ROLL THE DICE multiplierfeature, including “7Roll7,” “3BRoll3B,” “2BRoll2B,” “1 BRoll1B,”“ABRollAB” and “AnyRollCherry” and “UncleRollUncle.” In Table D-5 andthe description to follow, “Roll” is a shorthand notation for the WILDDICE symbol, “3B,” “2B,” “1B” and “AB” are shorthand notations for the 3BAR, 2 BAR, 1 BAR and ANY BAR symbols and “Uncle” is a shorthandnotation for the RICH UNCLE PENNYBAGS symbol.

[0183] The “Pay” column identifies payoff amounts associated with therespective combinations in Table D-5, for 1 coin played. In the case ofthe standard winning combinations, the payoff amounts are predeterminedamounts stored in system memory. For example, the “777” combination is astandard winning combination which will award 50 coins or credits in a1-coin game. In one embodiment, the coin awards are multiplied by twofor two coins bet and multiplied by three for three or four coins bet.The fourth coin allows the player the opportunity to play the MONOPOLYROLL & WIN™ bonus game and does not increase the value of the standardwinning combinations above the 3-coin payoff amount. Thus, for example,the “777” combination which, as noted above, will award 50 coins orcredits in a 1-coin game, will award 100 coins or credits in a 2-coingame and 150 coins or credits in a 3- or 4-coin game.

[0184] In the case of the combinations starting the ROLL & WIN bonusgame, the payoff amounts represent average payoff amounts which may beexpected in the bonus game. For example, the “UncleUncleUncle”combination will start the ROLL & WIN bonus game (if 4 coins or creditsare played) which will pay, on average, 81.08796 coins or credits.

[0185] In the case of the combinations including a “Roll” (WILD DICE)symbol, the payoff amounts represent the product of the standard payoff(or average bonus payoff) with various multiplier values 2 to 12 whichmight result from the ROLL THE DICE multiplier-bonus. For example, “27Roll7” is a shorthand notation for the 7, WILD DICE, 7 combinationwhich triggers the ROLL THE DICE feature, and in which a multiplierbonus of “2” is selected in the ROLL THE DICE feature. The payoff amountfor the “2 7Roll7” combination is 100, or twice the payoff of the “777”combination. Similary, “3 7Roll7” is a shorthand notation for the 7,WILD DICE, 7 combination in which a multiplier bonus of “3” is selectedin the ROLL THE DICE feature to triple the payoff of the “777”combination, and so forth.

[0186] With the exception of the “UncleRollUncle” combination, which isonly available for 4 coins played, the various combinations including a“Roll” (WILD DICE) symbol are multiplied by two for two coins bet andmultiplied by three for three or four coins bet. The fourth coin allowsthe player the opportunity to play the MONOPOLY ROLL & WIN™ bonus gameand does not increase the value of the standard winning combinationsabove the 3-coin payoff amount. Thus, for example, the “2 7Roll7”combination which, as noted above, will award 100 coins or credits in a1-coin game, will award 200 coins or credits in a 2-coin game and 300coins or credits in a 3- or 4-coin game.

[0187] The “Prob” column identifies, for the standard winningcombinations, the probabilities of hitting the outcomes in a singlespin. For the combinations including a WILD DICE (“Roll”) symbol, the“Prob” value takes into account the probability of rolling the indicatedmultiplier as well as the probability of “hitting” the indicatedoutcome. Where the reels each have twenty-two reel stop positions, as inthe ROLL & WIN™ game, there are 10,648 (22×22×22) possible symbolcombinations. The probability of hitting any particular combination in asingle spin is determined by dividing the number of possible “hits”associated with that combination (which is a function of the number ofreel positions of the symbols supporting that combination) by the totalnumber of possible combinations (i.e., 10,648). For example, considerthe “777” combination. Because there is one SEVEN symbol on reel 314,one SEVEN symbol on reel 316 and one SEVEN symbol on reel 318, there isone “hit” associated with that combination. The probability of hittingthat combination is therefore 9.39×10⁻⁵ (i.e. 1÷10,648).

[0188] Next consider the various “7Roll7” combinations. If the ROLL THEDICE multiplier is determined according to the roll of a pair of fairdice, the probability of selecting a “2×” or “12×” multiplier is 2.7%,the probability of selecting a “3×” or “11×” multiplier is 5.5%, theprobability of selecting a “4×” or “10×” multiplier is 8.3%, theprobability of selecting a “5×” or “9×” multiplier is 11.1%, theprobability of selecting a “6×” or “8×” multiplier is 13.9% and theprobability of selecting a “7×” multiplier is 16.7%. The probability of“hitting” the “2 7Roll7” and “12 7Roll7” combinations is therefore2.53×10⁻⁶ (i.e. 9.39×10⁻⁵×0.027). The remaining probabilities arecomputed in similar fashion.

[0189] The “EV” column identifies the normalized expected values of thevarious standard winning outcomes of Table D-2 for a 1-coin, 2-coin or3-coin game. These values are computed for each outcome by taking theproduct of the pay value (or average pay value) associated with thatoutcome and the probability associated with that outcome, divided by thenumber of coins played. Thus, for example, the “12 7Roll7” outcome has a1-coin expected value of 0.0015652 (600×2.6087×10⁻⁶÷1), a 2-coinexpected value of 0.0015652 (1200×2.6087×10⁻⁶÷2) and a 3-coin expectedvalue of 0.0015652 (1800×2.6087×10^(−6 ÷3)).

[0190] The “4thCoin” column identifies the normalized expected values ofthe various standard winning outcomes of Table D-2 for a 4-coin game.These values are computed in similar fashion as the 1-coin, 2-coin and3-coin expected values but differ because the pay value of the standardcombinations does not increase from a 3-coin to a 4-coin game. Thus, forexample, the “12 7Roll7” outcome has a 4-coin expected value of0.00117393 (1800×2.6087×10⁻⁶÷4).

[0191] Any of the gaming machines heretofore described can beimplemented with bonus-resource outcomes, causing the processor togenerate a deferred instruction which is exercisable to enhance theexcitement and/or winning expectation in the bonus game. Generally, thedeferred instruction associated with the bonus resource is exercisablein response to later outcomes or events in the game. For example, thebonus resource might might be obtained in response to special symbolcombination(s) the basic game and the deferred instruction associatedwith the bonus resource might be exercised in the bonus game. Thedeferred instruction might be executed automatically by the CPU inresponse to certain later-displayed indicia in the game or might beexercisable in response to player input. In one embodiment, the CPUcontinues to operate in the basic mode after the occurrence of abonus-resource outcome in the basic game. In this embodiment, any numberof bonus-resource outcomes may occur through several repetitions of thebasic game (causing the CPU to store a corresponding number of deferredinstructions in game memory) before entering the bonus mode. In oneembodiment, the CPU exercises the deferred instruction(s) associatedwith the bonus-resource(s), if at all, in the bonus game.

[0192] In one embodiment, the bonus game resource comprises a multiplier(e.g., 2×, 5×, 10×, etc.) associated with a deferred instruction tomultiply a later displayed value, such as an amount of coin(s) orcredit(s) otherwise awarded in a bonus game. For example, a “5×”resource, obtained as a result of a particular outcome of the basicgame, might be exercised in the bonus game to instruct the CPU tomultiply an otherwise-indicated award of 5 coins by five, resulting inan award of 25 coins. In another embodiment, the deferred instructionassociated with the bonus game resource comprises an “override” commandcausing the CPU to override or block the performance of an instructionotherwise indicated in the bonus game. For example, a deferred“override” command, obtained in the basic game as a result of aparticular bonus-resource outcome, might be played in the bonus game tooverride an “end-bonus” instruction encountered in the bonus game.Whereas the “end-bonus” instruction would otherwise have caused the CPUto end the bonus game, the exercise of the “override” command wouldallow the player to continue the bonus game. With particular referenceto the MONOPOLY-theme games described herein, one bonus-resource mightcomprise a “GET OUT OF JAIL FREE” card, obtainable as a result of aspecial symbol combination in the basic game and associated with adeferred instruction to “get out of jail,” or in other words to overridethe instruction nominally associated with the IN JAIL square. Thus, forexample, if the IN JAIL square is nominally associated with an“end-bonus” instruction, causing the CPU to end the bonus game, a playerlanding on the IN JAIL square might exercise a “GET OUT OF JAIL FREE”card to override the nominal end-bonus instruction and continue thebonus game.

[0193] It will be appreciated that the present invention has generallybeen described with reference to the particular games ADVANCE TOBOARDWALK™, REEL ESTATE™, ONCE AROUND™ and ROLL & WIN™, based on theMONOPOLY™ board game but is not limited to these particular games. Forexample, while the aforementioned games have a basic game in the form ofa slot machine, the present invention may be implemented with virtuallyany type of game of chance or skill or combination of such games havingoutcomes (e.g., “start-bonus” outcomes) which may trigger play of abonus game. The basic game may comprise, for example, a video poker orvideo blackjack game. Moreover, the present invention may be based onboard games other than MONOPOLY. Other variations within the scope ofthe present invention include basic games or bonus games with differentnumbers and types of reels and/or symbols, different paylineconfigurations, different values of coin awards, differentprobabilities, payback percentages, etc.
